WebAbout this book. The aim of this book is to present a formulation of the non-equilibrium physics in nanoscale systems in terms of many-body states and operators and, in addition, discuss a diagrammatic approach to Green functions expressed by many-body states. The intention is not to give an account of strongly correlated systems as such. WebGenerally, in the many body perturbation theory, there appear six kinds of Green functions, i.e., causal G c and anti-causal G c ¯; lesser G < and greater G > (Baym-Kadanoff type); retarded G R and advanced G A. Among them, information on the distribution function is embedded in the Baym-Kadanoff type, while information on the …
