This text introduces applied statistical mechanics by considering physically realistic models. After an accessible introduction to theories of thermal fluctuations and diffusion, Hans Pecseli applies them in a variety of physical contexts. The first part of the book is devoted to processes in thermal equilibrium, and considers linear systems. The fluctuation dissipation theorem, Fokker-Planck equations, and the Kramers-Kroenig relations are introduced during the course of the exposition. The scope is then expanded to include nonequilibrium systems and also illustrates simple nonlinear systems. | Fluctuations In Physical Systems by Hans L. Pécseli, Paperback | Indigo Chapters
