Nonreciprocal single-photon frequency converter via multiple semi-infinite coupled-resonator waveguides
Xun-Wei Xu, Ai-Xi Chen, Yong Li +1
We propose to construct a nonreciprocal single-photon frequency converter via multiple semi-infinite coupled-resonator waveguides (CRWs). We first demonstrate that the frequency of…

Phononic Josephson oscillation and self-trapping with two-phonon exchange interaction
Xun-Wei Xu, Ai-Xi Chen, Yu-xi Liu
We propose a bosonic Josephson junction (BJJ) in two nonlinear mechanical resonator coupled through two-phonon exchange interaction induced by quadratic optomechanical couplings. T…
