Loschmidt echo and stochastic-like quantum dynamics of nano-particles
V. A. Benderskii, L. A. Falkovsky, E. I. Kats
We investigate time evolution of prepared vibrational state (system) coupled to a reservoir with dense spectrum of its vibrational states. We assume that the reservoir has an equid…
Landau-Zener problem for energies close to potential crossing points
V. A. Benderskii, E. V. Vetoshkin, E. I. Kats
We examine one overlooked in previous investigations aspect of well - known Landau - Zener (LZ) problem, namely, the behavior in the intermediate, i.e. close to a crossing point, e…
Instanton versus traditional WKB approach to Landau - Zener problem
V. A. Benderskii, E. V. Vetoshkin, E. I. Kats
Different theoretical approaches to the famous two state Landau - Zener problem are briefly discussed. Apart from traditional methods of the adiabatic perturbation theory, Born - O…
