Grassmann Time-Evolving Matrix Product Operators for Quantum Impurity Models
Ruofan Chen, Xiansong Xu, Chu Guo
The time-evolving matrix product operators (TEMPO) method, which makes full use of the Feynman-Vernon influence functional, is the state-of-the-art tensor network method for bosoni…
Fidelity Out-of-Time-Order Correlator in the Spin-Boson Model
Ruofan Chen
In this article, using the numerically exact time-evolving matrix product operators method, we study the fidelity out-of-time-order correlator (FOTOC) in the unbiased spin-boson mo…
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…
Reexaming the ground state and magnetic properties of curium dioxide
Li Huang, Ruofan Chen, Haiyan Lu
The ground state electronic structure and magnetic behaviors of curium dioxide (CmO) are controversial. In general, the formal valence of Cm ions in CmO should be tetra…
