Book excerpt: Quantum Liquids contains lectures presented at the International School of Low Temperature Physics in Erice, Italy, on June 11-25, 1977. The book reviews developments in the study of superfluid phases of the 3He system and in the understanding of quasiparticles and their interactions in the Bose 4He system, along with recent work on the 3He-4He mixtures. Comprised of 10 chapters, this volume begins with an overview of the renormalization group theory, critical phenomena, and phase transition in superfluid helium. It then discusses the superfluid density and the nature of critical singularities, the theory and practice of neutron scattering, and scattering from weakly interacting quantum liquids. The reader is also introduced to the superfluidity of liquid helium films, light scattering from superfluid helium, and the theory of superfluid 3He. Other chapters focus on superfluid flow in helium-4 compared to that in helium-3, the physical properties of small droplets of helium as analogs of heavy nuclei, and experimental properties of superfluid 3He. Excitations in 3He-4He mixtures, bound excitations in liquid He4, and temperature dependence of the single roton energy and lifetime are also discussed. Physicists and students of physics will find this book extremely useful.

Book excerpt: Superfluidity is the jewel in the crown of low temperature physics. When temperatures are low enough, every substance in thermal equilibrium must become ordered. Since some materials remain fluid to the lowest temperatures, it is a fascinating question as to how this ordering can take place. One possibility is the formation of a superfluid state, a

This book was released on 2009-11-20 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first monograph that strives to give a complete and detailed description of the collective modes (CMs) in unconventional superfluids and superconductors (UCSF&SC). Using the most powerful method of modern theoretical physics OCo the path (functional) integral technique OCo authors build the three- and two-dimensional models for s -, p - and d -wave pairing in neutral as well as in charged FermiOCosystems, models of superfluid BoseOCosystems and FermiOCoBoseOComixtures. Within these models they study the collective properties of such systems as superfluid 3 He, superfluid 4 He, superfluid 3 He- 4 He mixtures, superfluid 3 He-films, superfluid 3 He and superfluid 3 He- 4 He mixtures in aerogel, high temperature superconductors, heavy-fermion superconductors, superconducting films etc. Authors compare their results with experimental data and predict a lot of new experiments on CMs study. This opens for experimentalists new possibilities for search of new intriguing features of collective behavior of UCSF&SC. The monograph creates the new scientific direction OCo the spectroscopy of collective modes in unconventional superfluids and superconductors. It will be useful for both theorists and experimentalists, studying superfluids and superconductors, low temperature physics, condensed matter physics, solid state physics. It could be used by graduate students specializing in the same areas. Sample Chapter(s). Introduction (162 KB). Chapter 1: Functional Integration Method (369 KB).

Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 of Novel Superfluids continues the presentation of recent results on superfluids, including novel metallic systems, superfluid liquids, and atomic/molecular gases of bosons and fermions, particularly when trapped in optical lattices. Since the discovery of superconductivity (Leyden, 1911), superfluid 4He (Moscow and Cambridge, 1937), superfluid 3He (Cornell, 1972), and observation of Bose-Einstein Condensation (BEC) of a gas (Colorado and MIT, 1995), the phenomenon of superfluidity has remained one of the most important topics in physics. Again and again, novel superfluids yield surprising and interesting behaviors. The many classes of metallic superconductors, including the high temperature perovskite-based oxides, MgB2, organic systems, and Fe-based pnictides, continue to offer challenges. The technical applications grow steadily. What the temperature and field limits are remains illusive. Atomic nuclei, neutron stars and the Universe itself all involve various aspects of superfluidity, and the lessons learned have had a broad impact on physics as a whole.

Book excerpt: This book reports on the latest developments in the field of Superfluidity. The phenomenon has had a tremendous impact on the fundamental sciences as well as a host of technologies. It began with the discovery of superconductivity in mercury in 1911, which was ultimately described theoretically by the theory of Bardeen Cooper and Schriever (BCS) in 1957. The analogous phenomena, superfluidity, was discovered in helium in 1938 and tentatively explained shortly thereafter as arising from a Bose-Einstein Condensation (BEC) by London. But the importance of superfluidity, and the range of systems in which it occurs, has grown enormously. In addition to metals and the helium liquids the phenomena has now been observed for photons in cavities, excitons in semiconductors, magnons in certain materials, and cold gasses trapped in high vacuum. It very likely exist for neutrons in a neutron star and, possibly, in a conjectured quark state at their center. Even the Universe itself can be regarded as being in a kind of superfluid state. All these topics are discussed by experts in the respective subfields.

Available in PDF, EPUB and Kindle. Book excerpt: Basic problems concerning the computer simulation of liquid metals in usual and extreme conditions with the use of interparticle potentials, mainly multi-particle potentials of the embedded atom model are considered in the book. The general questions of a structure of simple liquids, and the methods of simulation of non-crystalline systems (liquid and amorphous) - a method of molecular dynamics, Monte Carlo, quantum-mechanical modeling, etc. - are considered in the first five chapters. The types of interparticle potentials applied, the analysis of atomistic models, topological characteristics of liquids, and the results of modeling one-component and binary systems with the use of the simplest interparticle potentials are considered.In the second part of the book, a specification of interparticle interaction is given for 17 metals of the various groups of the periodic system with the use of the embedded atom model. Parameters of potentials under ambient pressure are found using the experimental data about properties of metal on the binodal, and for strongly compressed states via the metal properties found in Hugoniot adiabatic processes. The role of electronic terms in energy is considered in detail. Tables of the potentials are given in the Appendix. Then, thermodynamic, structural and diffusion properties of these metals in wide intervals of the pressure and temperatures are calculated (usually to hundreds of GPa and tens of thousands of Kelvin). The results of the calculations are tabulated.In the final chapters of the book, specific problems with respect to liquid metals are considered. Here, the problems of the structure and conditions in the center of the Earth, Moon and Jupiter satellites, calculations of shock adiabats, and the isotopic effect of diffusion are covered. The assessments of structure and temperature in the inner and outer cores of the Earth are given. Calculations of a series of shock adiabats for the initially porous or liquid metal samples are carried out, and questions of accuracy concerning the available experimental data are analyzed. Also, some non-classical mechanisms of liquid solidification, in particular, the cluster mechanism of solidification during strong overcooling, are discussed.The general problems of the thermodynamic description of nanoclusters are considered. The ambiguity of the use of the radius, volume, surface area and surface tension concepts for nanoclusters is shown, and a more reasonable approach is suggested. The series of nanoclusters of various sizes are constructed for several metals, and the dependence of their properties on the cluster size, including a melting temperature, are investigated. The possibility to compare the applicability of the Second Law of Thermodynamics in its usual form to the melting/solidification of nanoclusters is discussed. (Nova)
