Amplification of Weak Forces via Parametric Interactions and Non-Markovian Effects in Cavity Optomechanics
Y. F. Li, Ze Wang, W. Y. Hu +3
Weak force amplification describes the process of amplifying a faint low-frequency signal by means of an additional high-frequency modulation, which plays a vital role in quantum s…
Higher-Order Exceptional Points Induced by Non-Markovian Environments
H. Z. Shen, X. C. Zhang, L. Y. Ning +3
Exceptional points (EPs) are central to non-Hermitian physics because of their unique properties and broad application prospects. While extensively studied in parity-time ($\mathca…
Simultaneous nonreciprocal unconventional photon blockade via two degenerate optical parametric amplifiers in spinning resonators
J. X. Yang, Cheng Shang, Yan-Hui Zhou +1
We propose a scheme to achieving simultaneous nonreciprocal unconventional photon blockade in a system of two coupled spining resonators marked by modes a and b, each incorporating…
Dressed bound states and non-Markovian dynamics with a whispering-gallery-mode microcavity coupled to a two-level atom and a semi-infinite photonic waveguide
J. Y. Sun, C. Cui, Y. F. Li +4
We investigate the dressed bound states (DBS) in an open cavity with a whispering-gallery-mode microring coupled to a two-level atom and a waveguide with a mirror at the right end.…
Nonreciprocity and unidirectional invisibility in three optical modes with non-Markovian effects
H. Yi, T. Z. Luan, W. Y. Hu +4
In this work, we construct three coupled optical modes systems to obtain effective Hamiltonian mediated by coherent dissipative coupling during adiabatic elimination of large dissi…
Emergent Non-Markovian Gain in Open Quantum Systems
H. Z. Shen, Cheng Shang, Yan-Hui Zhou +1
Non-Markovian dynamics go beyond the Markovian approximation by capturing memory effects and information backflow in open quantum systems, which are crucial for describing realisti…
