Book excerpt: Cette thèse est dédiée aux effets de compétition entre le champ magnétique appliqué et la géométrie du pavage de réseaux de jonctions Josephson dans le cas particulier d'un pavage T3 ("dice"). Il s'agit en fait de l'étude d'un système modèle dans des conditions réelles. Le comportement des réseaux de jonctions classiques a été étudié en fonction du champ magnétique appliqué, de la température et de la fréquence avec laquelle le système est excité. Les propriétés de transport des réseaux de jonctions Josephson réalisées par effet de proximité sont mises en évidence par des mesures de l'impédance de surface effectuées au moyen d'une technique inductive qui distingue les travaux de recherche menés au sein du groupe. Selon la valeur du champ magnétique appliqué, il sera impossible pour le réseau de jonctions de se placer dans un minimum absolu d'énergie. Le système doit alors trouver un compromis entre les différentes contraintes liées à la fois au champ magnétique appliqué et à la géométrie du réseau. C'est dans une telle situation que le système est dit frustré. Le comportement est radicalement différent selon l'état de frustration, i.e. selon le champ magnétique appliqué. La particularité du pavage T3, composé de losanges orientés selon trois directions différentes, se manifeste lorsque le champ appliqué est tel que chaque losange du réseau est traversé par un demi quantum de flux. Dans ce cas la cohérence de phase, et par conséquent la supraconductivité, dans l'échantillon est presque supprimée et la dissipation est plus importante que pour n'importe quelle autre valeur de champ magnétique. Une comparaison entre cet état dit totalement frustré et un état qui au contraire présente une forte cohérence de phase a permis de révéler une riche variété de phénomènes. Les propriétés liées au modèle de mécanique statistique étudié, le modèle "XY", appliqué à cette géométrie particulière permettent de comprendre une partie seulement des observations. Il a donc été nécessaire.
Download or read book Statistical Mechanics written by James Sethna and published by OUP Oxford. This book was released on 2006-04-07 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: In each generation, scientists must redefine their fields: abstracting, simplifying and distilling the previous standard topics to make room for new advances and methods. Sethna's book takes this step for statistical mechanics - a field rooted in physics and chemistry whose ideas and methods are now central to information theory, complexity, and modern biology. Aimed at advanced undergraduates and early graduate students in all of these fields, Sethna limits his main presentation to the topics that future mathematicians and biologists, as well as physicists and chemists, will find fascinating and central to their work. The amazing breadth of the field is reflected in the author's large supply of carefully crafted exercises, each an introduction to a whole field of study: everything from chaos through information theory to life at the end of the universe.

Download or read book Introduction to Frustrated Magnetism written by Claudine Lacroix and published by Springer Science & Business Media. This book was released on 2011-01-12 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of highly frustrated magnetism has developed considerably and expanded over the last 15 years. Issuing from canonical geometric frustration of interactions, it now extends over other aspects with many degrees of freedom such as magneto-elastic couplings, orbital degrees of freedom, dilution effects, and electron doping. Its is thus shown here that the concept of frustration impacts on many other fields in physics than magnetism. This book represents a state-of-the-art review aimed at a broad audience with tutorial chapters and more topical ones, encompassing solid-state chemistry, experimental and theoretical physics.

This book was released on 2019-04-27 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum mechanics, the subfield of physics that describes the behavior of very small (quantum) particles, provides the basis for a new paradigm of computing. First proposed in the 1980s as a way to improve computational modeling of quantum systems, the field of quantum computing has recently garnered significant attention due to progress in building small-scale devices. However, significant technical advances will be required before a large-scale, practical quantum computer can be achieved. Quantum Computing: Progress and Prospects provides an introduction to the field, including the unique characteristics and constraints of the technology, and assesses the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems. This report considers hardware and software requirements, quantum algorithms, drivers of advances in quantum computing and quantum devices, benchmarks associated with relevant use cases, the time and resources required, and how to assess the probability of success.
Download or read book Thin Film Device Applications written by Kasturi Chopra and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional materials created ab initio by the process of condensation of atoms, molecules, or ions, called thin films, have unique properties significantly different from the corresponding bulk materials as a result of their physical dimensions, geometry, nonequilibrium microstructure, and metallurgy. Further, these characteristic features of thin films can be drasti cally modified and tailored to obtain the desired and required physical characteristics. These features form the basis of development of a host of extraordinary active and passive thin film device applications in the last two decades. On the one extreme, these applications are in the submicron dimensions in such areas as very large scale integration (VLSI), Josephson junction quantum interference devices, magnetic bubbles, and integrated optics. On the other extreme, large-area thin films are being used as selective coatings for solar thermal conversion, solar cells for photovoltaic conver sion, and protection and passivating layers. Indeed, one would be hard pressed to find many sophisticated modern optical and electronic devices which do not use thin films in one way or the other. With the impetus provided by industrial applications, the science and technology of thin films have undergone revolutionary development and even today continue to be recognized globally as frontier areas of RID work. Major technical developments in any field of science and technology are invariably accompanied by an explosion of published literature in the form of scientific publications, reviews, and books.

Download or read book How Can Physics Underlie the Mind written by George Ellis and published by Springer. This book was released on 2016-05-31 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physics underlies all complexity, including our own existence: how is this possible? How can our own lives emerge from interactions of electrons, protons, and neutrons? This book considers the interaction of physical and non-physical causation in complex systems such as living beings, and in particular in the human brain, relating this to the emergence of higher levels of complexity with real causal powers. In particular it explores the idea of top-down causation, which is the key effect allowing the emergence of true complexity and also enables the causal efficacy of non-physical entities, including the value of money, social conventions, and ethical choices.
Download or read book A Mind Over Matter written by Andrew Zangwill and published by Oxford University Press, USA. This book was released on 2021-01-08 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Mind Over Matter is a biography of the Nobel-prize winner Philip W. Anderson, a person widely regarded as one of the most accomplished and influential physicists of the second half of the twentieth century. Anderson (1923-2020) was a theoretician who specialized in the physics of matter, including window glass and metals, magnets and semiconductors, liquid crystals and superconductors. More than any other single person, Anderson transformed the patchwork subject of solid-state physics into the deep, subtle, and coherent discipline known today as condensed matter physics. Among his many world-class research achievements, Anderson discovered an aspect of wave physics that had been missed by all previous scientists going back to Isaac Newton. He became a public figure when he testified before Congress to oppose its funding of an expensive project intended exclusively for particle physics research. Over the years, he published many articles designed to influence a broad audience about issues where science impacted public policy and culture. Anderson grew up in the American mid-west, was educated at Harvard, and rose to the pinnacle of his profession during the first decade of his thirty-five career as a theoretical physicist at Bell Telephone Laboratories. Almost uniquely, he spent many years working half-time as a professor at the University of Cambridge and at Princeton University. The outspoken Anderson enjoyed broad influence outside of physics when he helped develop and champion the concepts of emergence and complexity as organizing principles to help attack very difficult problems in technically challenging disciplines.
