Numerical Approaches to Spatial Correlations in Strongly Interacting Fermion Systems
Spatial correlations are of fundamental importance for many fascinating aspects of solid state physics, such as non-Fermi-liquid behavior, spin fluctuations, high-temperature superconductivity and quantum criticality. The major part of this book is devoted to the dual fermion approach, which combines numerical and field theoretical diagrammatic methods to describe the effects of spatial correlations beyond dynamical mean-field theory (DMFT). The approach is generalized in various respects. It is shown that it has superior convergence properties compared to standard diagrammatic extensions of DMFT and its applicable even in presence of strong interactions. Numerical calculations employ the recently developed continuous-time quantum Monte Carlo methods, which are generalized to compute two-particle correlations functions. These techniques are used to study the two-plane Hubbard model on the Bethe lattice, the spatial correlations around a Kondo impurity and the Hubbard model in finite dimensions. Based on a ladder approximation to the dual-energy, a scheme is proposed which for the first time will allow a realistic and computationally feasible description of strongly correlated materials for which the correlations are manifestly long-ranged. In addition to the key scientific results, this book contains significant introductory materials to the models, methods and concepts used for the theoretical description of quantum many-particle systems. In particular the continuous-time quantum Monte Carlo methods are described in detail and on an elementary level. Providing technical details and complete derivations, this book is meant to help in the implementation of these novel approaches and to serve as an introduction and a reference for students beginning to work in this field.
Global Understanding of Accretion and Ejection around Black Holes
Accretion-ejection around compact objects, mainly around black holes, both in low mass, supermassive, and intermediate-mass, are rich and has been studied exhaustively. However, the subject is expanding and growing rapidly after the launch of different space-based satellites and ground-based telescopes in multiwavelength bands, leaving a range of questions on accretion and ejection mechanisms. The proper understanding of the underlying physical mechanisms responsible for observational evidence is still lacking for several reasons. With the advent of high-resolution satellite observations, it is possible to look at the problems globally as a complete package in a more consistent way. Recently, many new low mass black hole candidates have been discovered; however, very little is known about those systems, e.g., mass, spin parameter, and orbital period. The study in the spectro-temporal domain also needs proper understanding of spectral state change, quasi-periodic oscillation frequency evolution, hardness intensity diagram, and line emissions. The goal and motivation of this book are to focus on top-quality original works in the above-mentioned context, with important research facts that are written in a highly understandable way, from a theoretical, observational, and numerical simulation ground.This book is a collection of high-quality research work, which will give a compact and concise description of the overall view of the subject.
The Physics of Evolution
This book provides an introduction to the significant role of physics in evolution, based on the ideas of matter and energy resource flow, organism self-copying, and ecological change. The text employs these ideas to create quantitative models for important evolutionary processes.
