A graduate-level textbook in statistical physics and thermodynamics.This graduate-level book gives a self-contained exposition of fundamental topics in modern equilibrium and nonequilibrium statistical thermodynamics. The text follows a balanced approach between the macroscopic (thermodynamic) and microscopic (statistical) points of view. One notable feature of the book is the large number of problems. Simple applications are given in 71 exercises, while the student will find more elaborate challenges in 47 problems, some of which may be used as mini-projects. This advanced textbook will be of interest to graduate students and researchers in physics.This graduate-level book gives a self-contained exposition of fundamental topics in modern equilibrium and nonequilibrium statistical thermodynamics.
