Steady-state light-mechanical quantum steerable correlations in cavity optomechanics

Dissipative generation of significant amount of photon-phonon asymmetric steering in magnomechanical interfaces

“…Here we propose an effective approach for generating significant amount of entanglement and asymmetric steering between photon and phonon in a cavity magnomechanical system which consists of a microwave cavity mode, macroscopic magnon and phonon modes of a yttrium iron garnet sphere. Light-mechanical quantum steering [52][53][54] or steering between two massive mechanical oscillators [55][56][57] have been widely studied in cavity optomechanical systems, suggesting that photon-phonon or phonon-phonon one-way quantum steering can be achieved in such systems [54,56,57]. Primary researches also indicate that asymmetric steering between two magnons [47,49] can be obtained in cavity magnonics and asymmet-ric steering between a macroscopic mechanical oscillator and a magnon mode [50] can be obtained in a microwave-mediated phonon-magnon interface.…”

Bidirectional optical non-reciprocity in a multi-mode cavity optomechanical system

“…It has been accredited that the non-reciprocal signal transfer between two optical modes mediated by mechanical mode can be realized with suitable optical driving [20,21]. Additionally, these modes in cavity optomechanics can also result in some other interesting effecs like ground-state cooling of an NMR [22], steady-state light-mechanical quantum steerable correlations in a cavity optomechanical system (COS) [23], slow-to-fast light tuning and single-to-double optomechanically induced transparency (anlogous to electromagnetically induced transparency) [24], flexible manipulation on Goos-Hänchen shift as a classical application of COS [25], Fano resonances [26], superradiance [27], and optomechanically induced opaticity and amplification in a quadratically coupled COS [28]. Apart from that, Peterson et al have further demonstrated an efficient frequency-converting microwave isolator, stemmed on the optomechanical interactions between electromagnetic fields and a mechanically compliant vacuum-gap capacitor, which does not require a static magnetic field and allows a dynamic control of the direction of isolation [29].…”

Strong Squeezing of Duffing Oscillator in a Highly Dissipative Optomechanical Cavity System

“…Optomechanical system with the coupling between a cavity field and a macroscopic mechanical oscillator provides us a perfect platform for testing the quantum properties of macroscopic objects, such as macroscopic entanglement, [ 1–8 ] macroscopic steering, [ 9–11 ] macroscopic superposition, [ 12–14 ] macroscopic state transfer, [ 15,16 ] and macroscopic mechanical squeezing. [ 17–23 ] Meanwhile, due to the connection of mechanical motion and cavity field, optomechanical system can be used for high‐precision measurements, for instance ultrasensitive force detection, [ 24–26 ] angular velocity detection, [ 27,28 ] small quantities of adsorbed mass detection, [ 29–31 ] and gravitational wave detection.…”
