Generation and manipulation of phonon lasering in a two-drive cavity magnomechanical system

Abstract

A simple and feasible scheme for the generation and manipulation of phonon lasering is proposed and investigated based on a generic three-mode cavity magnomechanical system, in which a magnon mode couples simultaneously with a microwave cavity mode and a phonon mode. In sharp contrast to all previous phonon lasering schemes with only a single drive, the input pump field for the system in the proposed scheme is split into two microwave driving fields to drive the microwave cavity mode and the magnon mode, respectively. The impact of changing relative phase and relative amplitude ratio of the two microwave drives on mechanical gain, stimulated emitted phonon number, threshold power, and phonon emission line shape are theoretically and numerically investigated. The results indicate that the phonon laser action can be effectively controlled simply by adjusting the relative phase and relative amplitude ratio, so additional and tunable degrees of freedom are introduced to control the phonon laser. Considering the experimental feasibility of the generic cavity magnomechanical system and the two-drive approach, the present scheme provides a potentially practical route for the development of tunable phonon lasering devices with low-threshold, high-gain, and narrow-linewidth properties based on the platform of cavity magnomechanics.

Complete analysis of hyperentangled Bell state in three degrees of freedom using Kerr effect and self-assisted mechanism

“…Research has shown that the error probability is less than 10 −5 when αθ 2 > 9 [50], which indicates that our complete HBSA scheme can operate in the regime of weak cross-Kerr nonlinearity. It should be noted that the generation of Kerr nonlinearities in optical microcavities and magnonic systems has also been investigated recently [63,64]. Moreover, the cavity-assisted interaction and quantum dot spin in an optical microcavity may also provide accessible ways to build the photon number QND we required [65][66][67][68][69][70][71].…”

Cavity magnomechanics: from classical to quantum

“…CoFeB [59], which exhibits much stronger magnetostriction but also much larger magnon dissipation. As for mechanical amplification, phonon laser has also been theoretically studied [60][61][62][63][64], e.g. nonreciprocal [61] and exceptional-point-engineered [64] phonon laser are suggested.…”
