An important task of theoretical quantum physics is the building of idealized mathematical models to describe the properties of quantum matter. This text is an

The book introduces tools with which models of quantum matter are built. The most important technique, the Bethe ansatz, is developed in detail to perform exact

This book studies the widely used theoretical models for calculating properties of hot dense matter. Calculations are illustrated by plots and tables, and they

Providing a broad review of many techniques and their application to condensed matter systems, this book begins with a review of thermodynamics and statistical

This is an approachable introduction to the important topics and recent developments in the field of condensed matter physics. First, the general language of qu
