Magnomechanically induced transparency in the ferrimagnetic bridge crystal of atom opto-magnomechanical system
Wenting Diao, Xi Wang, Ke Di +5
We investigate the absorption and transmission properties of a weak probe field in an atom opto-magnomechanics system. The system comprises an assembly of two-level atoms and a mag…
Broadband squeezed light field by magnetostriction in an opto-magnomechanical
Ke Di, Shuai Tan, Anyu Cheng +3
We present a novel mechanism for generating a wide bandwidth squeezed optical output field in an opto-magnomechanical system. In this system, the magnon (mechanical) mode in the yt…
Entanglement enhancement of two different magnon modes via nonlinear effect in cavity magnomechanics
Ke Di, Xi Wang, Shuai Tan +4
We present a scheme to enhance two different magnon modes entanglement in cavity magnomechanics via nonlinear effect. The scheme demonstrated that nonlinear effects enhance entangl…
Dynamically tunable electromagnetically induced transparency-like metamaterial structure based on polarization sensitivity
Ke Di, Meng Xie, Zhaoyang Wang +3
In this paper, we propose a plasmon-induced transparency (PIT) metamaterial structure composed of Ag nanomaterials with polarization sensitivity. The metamaterial model consists of…
Macroscopic entanglement between ferrimagnetic magnons and atoms via crossed optical cavity
Ke Di, Xi Wang, Huarong Xia +4
We consider a two-dimensional opto-magnomechanical (OMM) system including two optical cavity modes, a magnon mode, a phonon mode, and a collection of two-level atoms. In this study…
