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…
Thermoelectric performance of topological boundary modes
Sina Böhling, Georg Engelhardt, Gloria Platero +1
We investigate quantum transport and thermoelectrical properties of a finite-size Su-Schrieffer-Heeger model, a paradigmatic model for a one-dimensional topological insulator, whic…
Topological Bogoliubov excitations in inversion-symmetric systems of interacting bosons
G. Engelhardt, T. Brandes
On top of the mean-field analysis of a Bose-Einstein condensate, one typically applies the Bogoliubov theory to analyze quantum fluctuations of the excited modes. Therefore, one ha…
