The Quantum Statistics of Dynamic Processes - Fick, Eugen

. .

Résumé :
The Quantum Statistics of Dynamic Processes gives an introduction to the essential methods and fields of application of this increasingly important branch of physics. Beginning with the basic concepts of statistical physics and quantum theory, the authors present a treatment of time-dependent external fields, deviations from equilibrium and equations of motion of the statistical operator. Exercises, hints for solution, and appendices are included....
