This book was released on 2003 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, A Finite Unified Quantum Field Theory of the Elementary Particle Standard Model and Quantum Gravity Based on New Quantum Dimensions and a New Paradigm in the Calculus of Variations, develops a new formulation of quantum field theory. Within this framework, a finite unified quantum field theory of the known forces of nature - electromagnetism, the weak interactions, the strong interactions and gravity - is created. The conventional Standard Model is the large distance limit of the elementary particle sector of the unified theory. The Quantum Gravity sector is finite in this formulation. Its large distance limit is Einsteinian gravity. This unified theory contains no divergences - thus solving a major problem that has bedeviled quantum field theory for the past seventy years. The theory is based on a new form of hidden dimensions: Quantum Dimensions, that only manifest themselves at ultra-high energies. Some new phenomena that result are: * Unification of QED, Weak Interactions, Strong Interactions and Quantum Gravity.* Finite - No divergences.* Finite also with massive vector bosons: No need for Higgs mechanism.* Low Energy Limit: Approximates Standard Model (and QED) to arbitrary accuracy.* Suggests possible doubly charged dilepton resonances.* Large Distance limit of Quantum Gravity: Newtonian gravitational potential.* No ultra-microscopic Black Holes.* A New form of hidden dimensions: Quantum Dimensions.* A New form of interaction: Dimensional Interactions.* A New paradigm (type of problem) for the Calculus of Variations.

Book excerpt: Named a Best Book of 2021 by the Financial Times and a Best Science Book of 2021 by The Guardian “Rovelli is a genius and an amazing communicator… This is the place where science comes to life.” ―Neil Gaiman “One of the warmest, most elegant and most lucid interpreters to the laity of the dazzling enigmas of his discipline...[a] momentous book” ―John Banville, The Wall Street Journal A startling new look at quantum theory, from the New York Times bestselling author of Seven Brief Lessons on Physics, The Order of Time, and Anaximander. One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the twenty-three-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious. As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness. Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better comprehend our place in it.

Download or read book Quantum Space written by Jim Baggott and published by Oxford University Press, USA. This book was released on 2018-11-22 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discovery of gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs. The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons and force-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs. But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity. Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes "the road less travelled": an approach which takes relativity as its starting point, and leads to a structure called Loop Quantum Gravity. Baggott tells the story through the careers and pioneering work of two of the theory's most prominent contributors, Lee Smolin and Carlo Rovelli. Combining clear discussions of both quantum theory and general relativity, this book offers one of the first efforts to explain the new quantum theory of space and time.
Download or read book Particles Fields and Forces written by Wouter Schmitz and published by Springer. This book was released on 2019-04-23 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can fundamental particles exist as waves in the vacuum? How can such waves have particle properties such as inertia? What is behind the notion of “virtual” particles? Why and how do particles exert forces on one another? Not least: What are forces anyway? These are some of the central questions that have intriguing answers in Quantum Field Theory and the Standard Model of Particle Physics. Unfortunately, these theories are highly mathematical, so that most people - even many scientists - are not able to fully grasp their meaning. This book unravels these theories in a conceptual manner, using more than 180 figures and extensive explanations and will provide the nonspecialist with great insights that are not to be found in the popular science literature.

Download or read book Symmetry and the Standard Model written by Matthew Robinson and published by Springer Science & Business Media. This book was released on 2011-08-17 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: While theoretical particle physics is an extraordinarily fascinating field, the incredibly fast pace at which it moves along, combined with the huge amount of background information necessary to perform cutting edge research, poses a formidable challenge for graduate students. This book represents the first in a series designed to assist students in the process of transitioning from coursework to research in particle physics. Rather than reading literally dozens of physics and mathematics texts, trying to assimilate the countless ideas, translate notations and perspectives, and see how it all fits together to get a holistic understanding, this series provides a detailed overview of the major mathematical and physical ideas in theoretical particle physics. Ultimately the ideas will be presented in a unified, consistent, holistic picture, where each topic is built firmly on what has come before, and all topics are related in a clear and intuitive way. This introductory text on quantum field theory and particle physics provides both a self-contained and complete introduction to not only the necessary physical ideas, but also a complete introduction to the necessary mathematical tools. Assuming minimal knowledge of undergraduate physics and mathematics, this book lays both the mathematical and physical groundwork with clear, intuitive explanations and plenty of examples. The book then continues with an exposition of the Standard Model of Particle Physics, the theory that currently seems to explain the universe apart from gravity. Furthermore, this book was written as a primer for the more advanced mathematical and physical ideas to come later in this series.
Download or read book Flow of Time written by Claus Birkholz and published by BookRix. This book was released on 2014-12-02 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Apply yesterday's variation principle to Gell-Mann's quarks, pepper it with the inconsistencies of unfounded ad-hoc tactics - and there you are with grandpa's classical "Standard" model having no strategy, no future, topped only by "string" fantasies "beyond" physics, with all the great questions left open. By marrying Planck's quanta with Einstein's General Relativity, the author is presenting the unified top-down model of a consistent "New Physics" (Quantum Gravity, including the Grand Unification) free of singularities and in accord with experiment. Space-time is bent, fully quantized and "background-independent". Old problems of fundamental physics emerge as self-explaining: 4-dimensionality, the quark confinement, flavours, cosmic inflation, the arrow of time, the physics of Black Holes with their event horizons, the origins of (ordinary and dark) matter, and much more is dropping out as self-evident properties of nature. Future starts to-day. Come along on the journey! The amazing success of "New Physics"/"Neue Physik" (with almost 10.000 copies sold in a single year) gave rise to this extended, 2nd edition renamed "Flow of Time". Main target groups: Students, physicists, mathematicians, but also people interested in philosophy or with an inclination to leave the beaten dead-end tracks of actual fundamental models of the old style in favour of more promising, novel ways.

Download or read book The Quantization of Gravity written by Claus Gerhardt and published by Springer. This book was released on 2018-04-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unified quantum theory incorporating the four fundamental forces of nature is one of the major open problems in physics. The Standard Model combines electro-magnetism, the strong force and the weak force, but ignores gravity. The quantization of gravity is therefore a necessary first step to achieve a unified quantum theory. In this monograph a canonical quantization of gravity has been achieved by quantizing a geometric evolution equation resulting in a gravitational wave equation in a globally hyperbolic spacetime. Applying the technique of separation of variables we obtain eigenvalue problems for temporal and spatial self-adjoint operators where the temporal operator has a pure point spectrum with eigenvalues $\lambda_i$ and related eigenfunctions, while, for the spatial operator, it is possible to find corresponding eigendistributions for each of the eigenvalues $\lambda_i$, if the Cauchy hypersurface is asymptotically Euclidean or if the quantized spacetime is a black hole with a negative cosmological constant. The hyperbolic equation then has a sequence of smooth solutions which are products of temporal eigenfunctions and spatial eigendistributions. Due to this "spectral resolution" of the wave equation quantum statistics can also be applied to the quantized systems. These quantum statistical results could help to explain the nature of dark matter and dark energy.
Download or read book A New Approach to Quantum Gravity written by Balungi Francis and published by Bill Stone Services. This book was released on 2018-06-27 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model is inconsistent with that of general relativity, to the point that one or both theories break down under certain conditions (for example within known space time singularities like the Big Bang and the centers of black holes beyond the event horizon). The appearance of singularities in any physical theory is an indication that something is wrong and that there is a need for new physics. Singularities can be avoided in GR and any field theory through the introduction of an efficient regularization procedure as this book directs. Regularization is a method of modifying observables which have singularities in order to make them finite by the introduction of a suitable parameter called regulator. The regulator, also known as a "cutoff", models our lack of knowledge about physics at unobserved scales (e.g. scales of small size or large energy levels). It compensates for the possibility that "new physics" (beyond the SM) may be discovered at those scales which the present theory is unable to model, while enabling the current theory to give accurate predictions as an "effective theory" within its intended scale of use. Therefore the main objective of this book is to discover new physics (Quantum Gravity) at those scales (or extra dimensions) which the General relativity theory and Quantum mechanics is unable to model. This has been achieved and remains the work of an experimenter to verify. While this is a new approach to quantum gravity, it reproduces the results in loop quantum gravity and string theory as the book indicates. This book provides a complete overview of quantum gravity from the frontiers of theoretical physics research for graduate students and researchers.
Download or read book ToE New Physics explaining our world by Quantum Gravity written by Claus Birkholz and published by BookRix. This book was released on 2016-01-08 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space, time, matter - what really is all that? What are charges, what flavours? What is preventing time from running backwards? Quantum Gravity is describing all that - consisely, comprehensively, to the point. The Grand Unified Theory (GUT = ToE = "Theory of Everything"), finally, is caring for the rest by relating all forces of nature to each other. Parities are the peep-holes into strange worlds before the Big Bang and beyond the event horizon. Everything is calculable, even the transitions there. By working out the value of the fine-structure constant, theory opens to recognizing Dark Matter as the cradle of visible matter; the GUT is demonstrating birth and properties of ordinary matter out of Dark Matter and by what its creation process is stopped again. A totally novel assessment is arising with respect to neutrino oscillations. Pauli's principle explains physically. Einstein's cosmological constant is demystified. Dark Energy, cosmic inflation, the number of dimensions we are living in are not any more dully accepted from outside - theory is deriving all that. As a matter of fact, the gateway to developing Quantum Gravity has been widely open since Einstein, Planck, and Dirac. Only, nobody has passed its threshold; nuclear fission had changed priorities. Then, Gell-Mann had knocked at the door of the GUT. This time, however, it was the "Standard" model to crash the door back into its frame, and the string model sealed the lock. - Meanwhile, the model succeeded in smuggling into the open underneath the feet of its jailers, ready for being applied more extensively.
Download or read book Understanding Gravity The Generation Model Approach written by Brian A Robson and published by World Scientific. This book was released on 2021-06-22 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, the General Theory of Relativity (GTR) describes the physics of the very large in terms of classical physics, while quantum theory describes the physics of the very small in terms of the Standard Model of particle physics. Unfortunately, the two theories are incompatible and do not describe satisfactorily all the forces between the various particles comprising ordinary matter. At present, one of the deepest problems in theoretical physics is harmonizing the GTR, which describes gravitation, with quantum mechanics, which describes the other three fundamental forces acting on the atomic scale. The main aim of the book is to provide an understanding of gravity in terms of a quantum theory given by the Generation Model of particle physics. The book presents a fully quantum theory of gravity, which describes both the large cosmological scale and the small atomic scale interactions between all particles.
