Najmeh Eshaqi Sani — University of Parma # Time reversibility of adiabatic process # We study the effect of time reversibility on the adiabatic preparation of populations in the few-level quantum system. The invariance of time-reversal symmetry implying reversibility in adiabatic processes is investigated by considering various sweep functions and system configurations. The Berry curvature and the transitions are pursued as a function of time. The results will be relevant for the optimization and acceleration of experimental protocols for efficient population transfer.
