Transitions at avoided level crossing with interaction and disorder
D. A. Garanin, R. Schilling
We investigate the influence of interaction between tunneling particles and disorder on their avoided-level-crossing transitions in the fast-sweep limit. Whereas the results confir…

Quantum Nonlinear Switching Model
D. A. Garanin, R. Schilling
We present a method, the dynamical cumulant expansion, that allows to calculate quantum corrections for time-dependent quantities of interacting spin systems or single spins with a…
