Time-Dependent Solution of the Generalized Fano Model
Gedeonová, Hedvika ; Kolorenč, Přemysl (advisor) ; Horáček, Jiří (referee)
In this thesis, the time evolution of Fano model, describing a discrete state embedded in a continuum of states with constant coupling, and generalized ver- sion of Fano model for an energy dependent coupling are investigated. For the time evolution of the generalized system, numerical simulation (Gaussian quadra- ture and numerical integration of a system of differential equations) is used. The system behaves as Fano model predicts when energy-dependent coupling tends to a constant one, and the system exponentially decays into the continuum. For a strongly energy-dependent coupling, the system oscillates between the initial discrete state and the continuum. The thesis provides numerically evaluated time evolution for different parameters of the coupling, brief interpretation of proba- bility oscillation phenomenon and study of the transition between oscillatory and non-oscillatory mode. 1
