Degenerate Landau-Zener model in the presence of quantum noise
arXiv:1907.11834 · doi:10.1142/S0219749919500497
Abstract
The degenerate Landau-Zener-Majorana-Stückelberg model consists of two degenerate energy levels whose energies vary with time and in the presence of an interaction which couples the states of the two levels. In the adiabatic limit, it allows for the populations transfer from states of one level to states of the other level. The presence of an interaction with the environment influences the efficiency of the process. Nevertheless, identification of possible decoherence-free subspaces permits to engineer coupling schemes for which quantum noise can be minimized.
