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…
Emergence of quasiparticle multiplets in curium
Li Huang, Ruofan Chen, Haiyan Lu
A combination of the density functional theory and the single-site dynamical mean-field theory is employed to study the electronic structures of various allotropes of elemental cur…
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…
