The task of the work is to develop effective mathematical methods of modern quantum field theory in nonperturbative approaches to the problems of theoretical nanophysics. Creating new universal approaches to solving Schrödinger equations in complex nanosystems that are exposed to external fields (electric, magnetic and electromagnetic). popup.nrat_date 2024-12-09 Close
