Available in PDF, EPUB and Kindle. Book excerpt: Until three decades ago, our understanding of the condensed matter systems were based on two frameworks developed by Russian physicist Lev Landau: his theory of phase transition, and Fermi liquids. The Landau theory of phase transition and the Fermi liquid theory together, can successfully explain a wide range of phenomena from ferromagnetism and antiferromagnetism to the conventional superconductivity. However, in the last thirty years, many experiments including the fractional quantum Hall effect (QHE) have revolutionized our view of nature. For a system of electrons that is subject to a very strong interactions and/or strong correlations between electrons, these two frameworks may break down. There many phases of matter, e.g. spin liquids, that do not break any classical symmetry, but are separated by phase transition. These states has the so called topological order. Also, many of these states do not follow predictions of the Fermi liquid theory and have many exotic behaviors. A rather powerful technique to handle with these issues is the slave particle method. In the first part of this thesis, using a more general slave particle method we study the strongly correlated Hubbard model, whose ground state may represent a Fermi liquid state at two spatial dimensions. We study the phase diagram of this model and show that the gapped spin liquid can be realized on the both honeycomb and square lattices, within mean-field. We also investigate the effective low energy theory of these states. Some of them are subject to compact gauge fluctuations. We study instanton effect in them and show that instanton proliferation can destabilize some of them. Another interesting problem in which we are interested in is the copper based high temperature superconductors (HTSC). The parent state of cuprates materials (undoped case) is a Mott insulator whose ground state is proposed to be a spin liquid. Upon doping, many exotic phases appear, from high temperature superconductivity to the pseudogap phase with disjoint Fermi segments (Fermi arcs) instead of a closed Fermi surface, or the strange metal phase where the Fermi liquid theory breaks down and exhibits very unusual transport properties. The isotope effect in these materials is also very different from that of conventional superconductors. In the second part of this thesis we study the above mentioned problem in detail and explain them by appealing to the slave particle method.

Book Synopsis Theoretical Methods for Strongly Correlated Electrons by : David Sénéchal
Download or read book Theoretical Methods for Strongly Correlated Electrons written by David Sénéchal and published by Springer Science & Business Media. This book was released on 2006-05-09 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the purely theoretical aspects of strongly correlated electrons, this volume brings together a variety of approaches to models of the Hubbard type - i.e., problems where both localized and delocalized elements are present in low dimensions. The chapters are arranged in three parts. The first part deals with two of the most widely used numerical methods in strongly correlated electrons, the density matrix renormalization group and the quantum Monte Carlo method. The second part covers Lagrangian, Functional Integral, Renormalization Group, Conformal, and Bosonization methods that can be applied to one-dimensional or weakly coupled chains. The third part considers functional derivatives, mean-field, self-consistent methods, slave-bosons, and extensions.

Book Synopsis Introduction to Many-Body Physics by : Piers Coleman
Download or read book Introduction to Many-Body Physics written by Piers Coleman and published by Cambridge University Press. This book was released on 2015-11-26 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: A modern, graduate-level introduction to many-body physics in condensed matter, this textbook explains the tools and concepts needed for a research-level understanding of the correlated behavior of quantum fluids. Starting with an operator-based introduction to the quantum field theory of many-body physics, this textbook presents the Feynman diagram approach, Green's functions and finite-temperature many-body physics before developing the path integral approach to interacting systems. Special chapters are devoted to the concepts of Fermi liquid theory, broken symmetry, conduction in disordered systems, superconductivity and the physics of local-moment metals. A strong emphasis on concepts and numerous exercises make this an invaluable course book for graduate students in condensed matter physics. It will also interest students in nuclear, atomic and particle physics.

This book was released on 2010-06-30 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since 1911, the Solvay Conferences have shaped modern physics. The 24th edition chaired by Bertrand Halperin did not break the tradition. Held in October 2008, it gathered in Brussels many of the leading figures in the “quantum theory of condensed matter”, addressing some of the most profound open problems in the field.The proceedings contain the “rapporteur talks” giving a broad overview with unique insights by distinguished renowned scientists. These lectures cover the five sessions treating: mesoscopic and disordered systems; exotic phases and quantum phase transitions in model systems; experimentally realized correlated-electron materials; quantum Hall systems, and one-dimensional systems; systems of ultra-cold atoms, and advanced computational methods.In the Solvay tradition, the proceedings include also the prepared comments to the rapporteur talks. The discussions among the participants — some of which are quite lively and involving dramatically divergent points of view — have been carefully edited and reproduced in full.
