Title Non-perturbative Description of Quantum Systems Author(s) Feranchuk, Ilya;Ivanov, Alexey;Le, Van-Hoang;Ulyanenkov, Alexander Publication Cham, Springer International Publishing, 2015. Description XV, 362 p. 63 illus., 43 illus. in color : online resource Abstract Note This book??introduces systematically the operator method for the solution of the Schr??dinger equation.??This method permits to describe the states of quantum systems in the entire range of parameters of Hamiltonian with a predefined accuracy. The operator method is unique compared??with other non-perturbative methods due to its ability to deliver in zeroth approximation the uniformly suitable estimate for both ground and excited states of quantum system. The method has been generalized for the application to quantum statistics and quantum field theory.?? In this book, the numerous applications of operator method for various physical systems are demonstrated. Simple models are used to illustrate the basic principles of the method which are further used for the solution of complex problems of quantum theory for many-particle systems. The results obtained are supplemented by numerical calculations, presented as tables and figures ISBN,Price 9783319130064 Keyword(s) 1. Atomic structure???? 2.
