Discontinuities in driven spin-boson systems due to coherent destruction of tunneling: breakdown of the Floquet-Gibbs distribution
Georg Engelhardt, Gloria Platero, Jianshu Cao
We show that the probability distribution of the stationary state of a dissipative ac-driven two-level system exhibits discontinuities, i.e. jumps, for parameters at which coherent…

Tuning the Aharonov-Bohm effect with dephasing in nonequilibrium transport
Georg Engelhardt, Jianshu Cao
The Aharanov-Bohm (AB) effect, which predicts that a magnetic field strongly influences the wave function of an electrically charged particle, is investigated in a three site syste…
