Non-Markovian effects in stochastic resonance in a two level system
Ruofan Chen, Xiansong Xu
Stochastic resonance is a phenomenon where the response signal to external driving is enhanced by environment noise. In quantum regime, the effect of environment is often intrinsic…
Heat Current in Non-Markovian Open Systems
Ruofan Chen
We generalize time-evolving matrix product operators method to nonequilibrium quantum transport problems. The nonequilibrium current is obtained via numerical differentiation of th…
Landau-Zener transitions in a fermionic dissipative environment
Ruofan Chen
We study Landau-Zener transitions in a fermionic dissipative environment where a two-level (up and down states) system is coupled to two metallic leads kept with different chemical…
Dissipative features of the driven spin-fermion system
Ruofan Chen, Xiansong Xu
We study a generic spin-fermion model, where a two-level system (spin) is coupled to two metallic leads with different chemical potentials, in the presence of monochromatic driving…
Electronic Bloch oscillation in a pristine monolayer graphene
Tongyun Huang, Ruofan Chen, Tianxing Ma +2
In a pristine monolayer graphene subjected to a constant electric field along the layer, the Bloch oscillation of an electron is studied in a simple and efficient way. By using the…
