Microwave-optics entanglement is a vital component for building hybrid quantum networks. Here, a new mechanism for preparing stationary entanglement between microwave and optical cavity fields in a cavity optomagnomechanical system is proposed. It consists of a magnon mode in a ferrimagnetic crystal that couples directly to a microwave cavity...

Nanomechanical resonators made from graphene are widely researched for their potential applications due to their high sensitivity. Their atomic scale thickness makes it that these resonators exhibit amplitude-dependent damping at relatively small driving forces. To further increase the performance of these devices, it is essential to understand...
