Adiabatic Transitions in a Two-Level System Coupled to a Free Boson Reservoir

Joye, Alain; Merkli, Marco; Spehner, Dominique

Abstract

We consider a time-dependent two-level quantum system interacting with a free Boson reservoir. The coupling is energy conserving and depends slowly on time, as does the system Hamiltonian, with a common adiabatic parameter epsilon. Assuming that the system and reservoir are initially decoupled, with the reservoir in equilibrium at temperature T >= 0, we compute the transition probability from one eigenstate of the twolevel system to the other eigenstate as a function of time, in the regime of small e and small coupling constant.. We analyse the deviation from the adiabatic transition probability obtained in the absence of the reservoir.
