Abstract Phonon lasers, which exploit coherent amplifications of phonons, are a means to explore nonlinear phononics, image nanomaterial structures and operate phononic devices. Recently, phonon laser governed by dispersive optomechanical coupling has been demonstrated levitating nanosphere in an optical tweezer. Such levitated devices, with minimal noise high vacuum, can allow flexible control large-mass objects without any internal discrete energy levels. However, it is challenging achieve...

In this work, we demonstrate how the magnon Kerr effect can be harnessed generate control nonreciprocal in cavity optomagnomechanics (COMM). This induces frequency shifts introduces pair-magnon interactions, both of which are tunable through magnetic field direction, enabling behavior. By adjusting...
We study the cross-Kerr (CK) effect on an optomechanical system driven by two-tone fields. show that in presence of CK effect, a bistable behavior mean photon number cavity becomes more robust against fluctuations frequency detuning between mode and control field. The bistability can also be turned into tristability within experimentally accessible range parameters. Also, we find symmetric profile optomechanically induced transparency is broken zero-absorption point shifted effect. This...
Strong long-range coupling between distant spins is crucial for spin-based quantum information processing. However, achieving such a strong spin-spin remains challenging. Here we propose to realize two via the Kerr effect of magnons in yttrium-iron-garnet nanosphere. By applying microwave field on this nanosphere, can induce magnon squeezing, so that spin and squeezed be exponentially enhanced. This turn allows spin-magnon distance increase from nano- micrometer scale. considering virtual...

The considered cavity-magnon system consists a three-dimensional microwave containing two yttrium iron garnet (YIG) spheres, where modes (one has MKN, while other is linear) YIG spheres are simultaneously coupled photons. To obtain effective gain mode, we feed input fields into cavity. By choosing appropriate parameters, coherent perfect absorption occurs, and can be described by an...

By eliminating mode, position-position two-mode squeezing are induced. In representation, spin-photon, magnon-photon, photon-photon strengths...
The superradiant phase transition (SPT) has been widely studied in cavity quantum electrodynamics (CQED). However, this SPT is still subject to ongoing debates due the no-go theorem induced by so-called ${\mathbf{A}}^{2}$ term (AT). We propose a hybrid system, consisting of single-mode simultaneously coupled both two-level system and yttrium-iron-garnet sphere supporting magnons with Kerr nonlinearity, restore against AT. here can effectively introduce an additional AT tunable strong enough...
Realizing optical trapping enhancement is crucial in biomedicine, fundamental physics, and precision measurement. Taking the metamaterials with artificially engineered permittivity as photonic force probes tweezers will offer unprecedented opportunities for trap enhancement. However, it usually involves multi-parameter optimization requires lengthy calculations; thereby few studies remain despite decades of research on tweezers. Here, we introduce a deep learning (DL) model to attack this...
