Light as quantum back-action nullifying meter
Sankar Davuluri, Yong Li
We propose a new method to overcome quantum back-action in a measurement process using oscillators. An optical oscillator is used as a meter to measure the parameters of another op…
Giant atoms with time-dependent couplings
Lei Du, Yao-Tong Chen, Yan Zhang +1
We study the decay dynamics of a two-level giant atom that is coupled to a waveguide with time-dependent coupling strengths. In the non-Markovian regime where the retardation effec…
Enhancing the force sensitivity of squeezed light optomechanical interferometer
Sreeshna Subhash, Sanket Das, Tarak Nath Dey +2
Application of frequency-dependent squeezed vacuum improves the force sensitivity of optomechanical interferometer beyond the standard quantum limit by a factor of , where…
Nonreciprocal light transmission via optomechanical parametric interactions
Yan-Ting Lan, Wan-Jun Su, Huaizhi Wu +2
Nonreciprocal transmission of optical or microwave signals is indispensable in various applications involving sensitive measurements. In this paper, we study optomechanically induc…
Nonreciprocal frequency conversion with chiral -type atoms
Lei Du, Yao-Tong Chen, Yong Li
In this paper, we begin with a model of a -type atom whose both transitions are chirally coupled to a waveguide and then extend the model to its giant-atom version. We investiga…
Single-photon frequency conversion via a giant -type atom
Lei Du, Yong Li
We study single-photon scattering via a giant -type atom, where both atomic transitions are coupled with the modes of a single waveguide at two separated points. The giant-atom…
