Tunable photon-photon correlations in waveguide QED systems with giant atoms
Wenju Gu, Lei Chen, Zhen Yi +2
We investigate the scattering processes of two photons in a one-dimensional waveguide coupled to two giant atoms. By adjusting the accumulated phase shifts between the coupling poi…
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…
Quantum nonlinear cavity QED with coherently prepared atoms
Guoqing Yang, Wen-ju Gu, Gaoxiang Li +2
We propose a method to study the quantum nonlinearity and observe the multiphoton transitions in a multiatom CQED system. We show that by inducing simultaneously destructive quantu…
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…
Establishment of correlated states in a quantum dot interacting with an acoustic phonon reservoir
Hui Huang, Gao-xiang Li, Wen-ju Gu +1
We investigate the effects of a low frequency (acoustic) phonon bath on the dynamics of a quantum dot modelled as a cascade three-level system. We show that the phonon bath appears…
Squeezing of a movable mirror via the dissipative optomechanical coupling
Wen-ju Gu, Gao-xiang Li, Ya-ping Yang
We investigate the squeezing for a movable mirror in the dissipative optomechanics in which the oscillating mirror modulates both the resonance frequency and the linewidth of the c…
Generating coherence and entanglement with a finite-size atomic ensemble in a ring cavity
Li-hui Sun, Gao-xiang Li, Wen-ju Gu +1
We propose a model to study the coherence and entanglement resulting from the interaction of a finite-size atomic ensemble with degenerate counter-propagating field modes of a high…
