Book excerpt: The physics of the beginning of the 20th century experienced two major conceptual revolutions that changed the way we see the world. General relativity, on the one hand, describes space-time on a large scale; quantum mechanics, on the other hand, deals with the microscopic behaviour of matter. Since then, physicists have been looking for a theory of quantum gravity, which would bring the two languages together. It is expected that such a theory profoundly changes our understanding of black holes, these extremely dense astrophysical objects, long remained in the shade of calculations, and now observed in droves in the sky. Quantum theory has already shown, as a first approximation, that a black hole slowly evaporates. Quantum gravity also predicts that such an object could metamorphose into a white hole, its time-reverse. In this thesis, we study the foundations of such a scenario and propose a mathematical model that includes the phenomenon of evaporation.

Download or read book Analogue Quantum Simulation written by Dominik Hangleiter and published by Springer Nature. This book was released on 2022-01-21 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents fresh insights into analogue quantum simulation. It argues that these simulations are a new instrument of science. They require a bespoke philosophical analysis, sensitive to both the similarities to and the differences with conventional scientific practices such as analogical argument, experimentation, and classical simulation. The analysis situates the various forms of analogue quantum simulation on the methodological map of modern science. In doing so, it clarifies the functions that analogue quantum simulation serves in scientific practice. To this end, the authors introduce a number of important terminological distinctions. They establish that analogue quantum ‘computation' and ‘emulation' are distinct scientific practices and lead to distinct forms of scientific understanding. The authors also demonstrate the normative value of the computation vs. emulation distinction at both an epistemic and a pragmatic level. The volume features a range of detailed case studies focusing on: i) cold atom computation of many-body localisation and the Higgs mode; ii) photonic emulation of quantum effects in biological systems; and iii) emulation of Hawing radiation in dispersive optical media. Overall, readers will discover a normative framework to isolate and support the goals of scientists undertaking analogue quantum simulation and emulation. This framework will prove useful to both working scientists and philosophers of science interested in cutting-edge scientific practice.
Download or read book Analogue Gravity Phenomenology written by Daniele Faccio and published by Springer. This book was released on 2013-08-13 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analogue Gravity Phenomenology is a collection of contributions that cover a vast range of areas in physics, ranging from surface wave propagation in fluids to nonlinear optics. The underlying common aspect of all these topics, and hence the main focus and perspective from which they are explained here, is the attempt to develop analogue models for gravitational systems. The original and main motivation of the field is the verification and study of Hawking radiation from a horizon: the enabling feature is the possibility to generate horizons in the laboratory with a wide range of physical systems that involve a flow of one kind or another. The years around 2010 and onwards witnessed a sudden surge of experimental activity in this expanding field of research. However, building an expertise in analogue gravity requires the researcher to be equipped with a rather broad range of knowledge and interests. The aim of this book is to bring the reader up to date with the latest developments and provide the basic background required in order to appreciate the goals, difficulties, and success stories in the field of analogue gravity. Each chapter of the book treats a different topic explained in detail by the major experts for each specific discipline. The first chapters give an overview of black hole spacetimes and Hawking radiation before moving on to describe the large variety of analogue spacetimes that have been proposed and are currently under investigation. This introductory part is then followed by an in-depth description of what are currently the three most promising analogue spacetime settings, namely surface waves in flowing fluids, acoustic oscillations in Bose-Einstein condensates and electromagnetic waves in nonlinear optics. Both theory and experimental endeavours are explained in detail. The final chapters refer to other aspects of analogue gravity beyond the study of Hawking radiation, such as Lorentz invariance violations and Brownian motion in curved spacetimes, before concluding with a return to the origins of the field and a description of the available observational evidence for horizons in astrophysical black holes.

Download or read book Formation and Evolution of Black Holes in the Galaxy written by Gerald Edward Brown and published by World Scientific. This book was released on 2003 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: In published papers H A Bethe and G E Brown worked out the collapse of large stars and supernova explosions. They went on to evolve binaries of compact stars, finding that in the standard scenario the first formed neutron star always went into a black hole in common envelope evolution. C-H Lee joined them in the study of black hole binaries and gamma ray bursts. They found the black holes to be the fossils of the gamma ray bursts. From their properties they could reconstruct features of the burst and of the accompanying hypernova explosions. This invaluable book contains 23 papers on astrophysics, chiefly on compact objects, written over 23 years. The papers are accompanied by illuminating commentary. In addition there is an appendix on kaon condensation which the editors believe to be relevant to the equation of state in neutron stars, and to explain why black holes are formed at relatively low masses.

Download or read book White Holes written by Carlo Rovelli and published by Penguin. This book was released on 2023-10-31 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mesmerizing trip to the strange world of white holes from the bestselling author of Seven Brief Lessons on Physics and The Order of Time Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole’s core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. In White Holes, he reveals the mind of a scientist at work. He traces the ongoing adventure of his own cutting-edge research, investigating whether all black holes could eventually turn into white holes, equally compact objects in which the arrow of time is reversed. Rovelli writes just as compellingly about the work of a scientist as he does the marvels of the universe. He shares the fear, uncertainty, and frequent disappointment of exploring hypotheses and unknown worlds, and the delight of chasing new ideas to unexpected conclusions. Guiding us beyond the horizon, he invites us to experience the fever and the disquiet of science—and the strange and startling life of a white hole.

Download or read book The Cosmic Web written by N. Katherine Hayles and published by Cornell University Press. This book was released on 2018-03-15 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the central concept of the field—which depicts the world as a mutually interactive whole, with each part connected to every other part by an underlying field— have come models as diverse as quantum mathematics and Saussure’s theory of language. In The Cosmic Web, N. Katherine Hayles seeks to establish the scope of the field concept and to assess its importance for contemporary thought. She then explores the literary strategies that are attributable directly or indirectly to the new paradigm; among the texts at which she looks closely are Robert Pirsig’s Zen and the Art of Motorcycle Maintenance, Nabokov’s Ada, D. H. Lawrence’s early novels and essays, Borges’s fiction, and Thomas Pynchon’s Gravity’s Rainbow.
