Download or read book High Precision Optical Spectroscopy and Quantum State Selected Photodissociation of Ultracold 88Sr2 Molecules in an Optical Lattice written by Mickey McDonald and published by Springer. This book was released on 2017-11-18 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis unites the fields of optical atomic clocks and ultracold molecular science, laying the foundation for optical molecular measurements of unprecedented precision. Building upon optical manipulation techniques developed by the atomic clock community, this work delves into attaining surgical control of molecular quantum states. The thesis develops two experimental observables that one can measure with optical-lattice-trapped ultracold molecules: extremely narrow optical spectra, and angular distributions of photofragments that are ejected when the diatomic molecules are dissociated by laser light pulses. The former allows molecular spectroscopy approaching the level of atomic clocks, leading into molecular metrology and tests of fundamental physics. The latter opens the field of ultracold chemistry through observation of quantum effects such as matter-wave interference of photofragments and tunneling through reaction barriers. The thesis also describes a discovery of a new method of thermometry that can be used near absolute zero temperatures for particles lacking cycling transitions, solving a long-standing experimental problem in atomic and molecular physics.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes how the rich internal degrees of freedom of molecules can be exploited to construct the first “clock” based on ultracold molecules, rather than atoms. By holding the molecules in an optical lattice trap, the vibrational clock is engineered to have a high oscillation quality factor, facilitating the full characterization of frequency shifts affecting the clock at the hertz level. The prototypical vibrational molecular clock is shown to have a systematic fractional uncertainty at the 14th decimal place, matching the performance of the earliest optical atomic lattice clocks. As part of this effort, deeply bound strontium dimers are coherently created, and ultracold collisions of these Van der Waals molecules are studied for the first time, revealing inelastic losses at the universal rate. The thesis reports one of the most accurate measurements of a molecule’s vibrational transition frequency to date. The molecular clock lays the groundwork for explorations into terahertz metrology, quantum chemistry, and fundamental interactions at atomic length scales.

Available in PDF, EPUB and Kindle. Book excerpt: Quantum computers, though not yet available on the market, will revolutionize the future of information processing. Quantum computers for special purposes like quantum simulators are already within reach. The physics of ultracold atoms, ions and molecules offer unprecedented possibilities of control of quantum many body systems and novel possibilities of applications to quantum information processing and quantum metrology. Particularly fascinating is the possibility of using ultracold atoms in lattices to simulate condensed matter or even high energy physics. This book provides a complete and comprehensive overview of ultracold lattice gases as quantum simulators. It opens up an interdisciplinary field involving atomic, molecular and optical physics, quantum optics, quantum information, condensed matter and high energy physics. The book includes some introductory chapters on basic concepts and methods, and then focuses on the physics of spinor, dipolar, disordered, and frustrated lattice gases. It reviews in detail the physics of artificial lattice gauge fields with ultracold gases. The last part of the book covers simulators of quantum computers. After a brief course in quantum information theory, the implementations of quantum computation with ultracold gases are discussed, as well as our current understanding of condensed matter from a quantum information perspective.

Book excerpt: For more than a century, studies of atomic hydrogen have been a rich source of scientific discoveries. These began with the Balmer series in 1885 and the early quantum theories of the atom, and later included the development of QED and the first successful gauge field theory. Today, hydrogen and its relatives continue to provide new fundamental information, as witnessed by the contributions to this book. The printed volume contains invited reviews on the spectroscopy of hydrogen, muonium, positronium, few-electron ions and exotic atoms, together with related topics such as frequency metrology and the determination of fundamental constants. The accompanying CD contains, in addition to these reviews, a further 40 contributed papers also presented at the conference "Hydrogen Atom 2" held in summer 2000. Finally, to facilitate a historical comparison, the CD also contains the proceedings of the first "Hydrogen Atom" conference of 1988. The book includes a foreword by Norman F. Ramsey.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first detailed account of a new approach to microphysics based on two leading ideas: (i) the explicit dependence of physical laws on scale encountered in quantum physics, is the manifestation of a fundamental principle of nature, scale relativity. This generalizes Einstein's principle of (motion) relativity to scale transformations; (ii) the mathematical achievement of this principle needs the introduction of a nondifferentiable space-time varying with resolution, i.e. characterized by its fractal properties.The author discusses in detail reactualization of the principle of relativity and its application to scale transformations, physical laws which are explicitly scale dependent, and fractals as a new geometric description of space-time.

Download or read book Quantum Chemistry written by Ajit Thakkar and published by Morgan & Claypool Publishers. This book was released on 2017-10-03 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides non-specialists with a basic understanding ofthe underlying concepts of quantum chemistry. It is both a text for second or third-year undergraduates and a reference for researchers who need a quick introduction or refresher. All chemists and many biochemists, materials scientists, engineers, and physicists routinely user spectroscopic measurements and electronic structure computations in their work. The emphasis of Quantum Chemistry on explaining ideas rather than enumerating facts or presenting procedural details makes this an excellent foundation text/reference. The keystone is laid in the first two chapters which deal with molecular symmetry and the postulates of quantum mechanics, respectively. Symmetry is woven through the narrative of the next three chapters dealing with simple models of translational, rotational, and vibrational motion that underlie molecular spectroscopy and statistical thermodynamics. The next two chapters deal with the electronic structure of the hydrogen atom and hydrogen molecule ion, respectively. Having been armed with a basic knowledge of these prototypical systems, the reader is ready to learn, in the next chapter, the fundamental ideas used to deal with the complexities of many-electron atoms and molecules. These somewhat abstract ideas are illustrated with the venerable Huckel model of planar hydrocarbons in the penultimate chapter. The book concludes with an explanation of the bare minimum of technical choices that must be made to do meaningful electronic structure computations using quantum chemistry software packages.

Download or read book Dispositional Pluralism written by Jennifer McKitrick and published by Oxford University Press. This book was released on 2018 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jennifer McKitrick offers an opinionated guide to the philosophy of dispositions. In her view, when an object has a disposition, it is such that, if a certain type of circumstance were to occur, a certain kind of event would occur. Since it is very common for this to be the case for a variety of reasons, dispositions are very abundant and diverse. They include such varied properties as character traits like a hero's courage, characteristics of physical objects like a wine glass's fragility, and characteristics of microphysical entities like an electron's charge. Some dispositions are natural while others are non-natural. Some dispositions called "powers" are ungrounded while non-fundamental dispositions are grounded in other properties. Some dispositions manifest constantly, some of them manifest spontaneously, while others manifest only when they are triggered to do so. Some dispositions manifest by causing another dispositional property to be instantiated, while others have manifestations that involve non-dispositional properties and relations. Some dispositions are intrinsic to their bearers while others are extrinsic. Some of them are causally relevant to their manifestations while others are not. Some dispositions manifest in some particular way in particular circumstances, while other dispositions manifest in various ways in various circumstances. What makes all of these diverse properties dispositions is their connection to a certain kind of counterfactual fact. Nevertheless, disposition ascriptions are not semantically reducible to counterfactual claims.
Download or read book Perceptual Ephemera written by Thomas Crowther and published by Oxford University Press. This book was released on 2018-05-31 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most research on perception has focused on the perceptual experience of three-dimensional, solid, bounded, and coherent material objects - items like tables and tomatoes. But as well as having perceptual experience of such objects, we also experience such aspects of the world as, for instance, rainbows and surfaces, shadows and absences: things that are ephemeral by contrast with material objects. This book presents fifteen new essays on the perceptual experience of such ephemera. The editors' introduction provides a detailed guide to the topic as a whole, setting out the thematic background to this emerging area of research in contemporary philosophy of perception. The volume winds a path through the ephemeral, considering such topics as sounds, smells, transparency, reflection, camouflage, solidity, and ambient vision. A general aim of the volume is to make a case that the broad range of ephemera it catalogues is far from marginal, or insubstantial with respect to their philosophical interest and value. Philosophical attention to perceptul ephemera may well suggest novel routes to arriving at a more developed understanding of perceptual experience at large and its characteristic features.
Download or read book To Kill a Sultan written by Houssine Alloul and published by Springer. This book was released on 2017-11-07 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores an event described by the Times as 'one of the greatest and most sensational political conspiracies of modern times'. On 21 July 1905, just after the Friday Prayer at the Yıldız Hamidiye Mosque in Istanbul, a car bomb exploded and left 26 dead with another 58 wounded. Sultan Abdülhamid II, the target of the attack, remained unscathed. The Ottoman police soon discovered that Armenian revolutionaries were behind the plot and several people were arrested and convicted, among them the Belgian anarchist Edward Joris. His incarceration sparked international reaction and created a diplomatic conflict. The assassination attempt failed, the events faded from memory, and the plot became a footnote in early twentieth-century history. This book rediscovers the conspiracy as a transnational moment in late Ottoman history, opening a window on key themes in modern history, such as international law, terrorism, Orientalism, diplomacy, anarchism, imperialism, nationalism, mass media and humanitarianism. It provides an original look on the many trans- and international links between the Ottoman Empire, Europe and the rest of the world at the start of the twentieth century. cdscds
