Strongly correlated two-photon transport in a one-dimensional waveguide coupled to a weakly nonlinear cavity
Xun-Wei Xu, Yong Li
We study the photon-photon correlation properties of two-photon transport in a one-dimensional waveguide coupled to a nonlinear cavity via a real-space approach. It is shown that t…
Tunable photon statistics in weakly nonlinear photonic molecules
Xun-Wei Xu, Yong Li
In recent studies [Liew et al., Phys. Rev. Lett. 104, 183601 (2010); Bamba et al., Phys. Rev. A 83, 021802(R) (2011)], due to destructive interference between different paths for t…
Strong photon antibunching of symmetric and antisymmetric modes in weakly nonlinear photonic molecules
Xun-Wei Xu, Yong Li
We study the photon statistics of symmetric and antisymmetric modes in a photonic molecule consisting of two linearly coupled nonlinear cavity modes. Our calculations show that str…
Renormalized quantum Fisher information manifestation of Berezinskii-Kosterlitz-Thouless phase transition for spin-1/2 XXZ chain
Qiang Zheng, Yao Yao, Xun-Wei Xu +1
Combining the ideas of quantum Fisher information and quantum renormalization group method, the Berezinskii-Kosterlitz-Thouless quantum phase transition of spin- 1/2 XXZ chain is i…
Quantum Nonlinear Optics Near Optomechanical Instabilities
Xunnong Xu, Michael Gullans, Jacob M. Taylor
Optomechanical systems provide a unique platform for observing quantum behavior of macroscopic objects. However, efforts towards realizing nonlinear behavior at the single photon l…
Mechanical PT symmetry in coupled optomechanical systems
Xun-Wei Xu, Yu-xi Liu, Chang-Pu Sun +1
We propose to realize mechanical parity-time PT symmetry in two coupled optomechanical systems. To provide gain to one mechanical resonator and the same amount of damping to the ot…
