Correlated two-photon scattering in a one-dimensional waveguide coupled to two- or three-level giant atoms
Wenju Gu, He Huang, Zhen Yi +3
We study the two-photon scattering processes in a one-dimensional waveguide coupled to a two- or three-level giant atom, respectively. The accumulated phase shift between the two c…

Mechanical cooling in the single-photon quadratical optomechanics
Wen-ju Gu, Zhen Yi, Li-hui Sun +1
In the paper we study the nonlinear mechanical cooling processes in the intrinsic quadratically optomechanical coupling system without linearizing the optomechanical interaction. W…

Nullity of quantum discord of two-qubit X-state systems
Gao-xiang Li, Zhen Yi, Zbigniew Ficek
The conditions are established for nullity of quantum discord for mixed states of a general two-qubit system whose dynamical behaviour is given by an X-state form density matrix. I…
