Nonreciprocal magnon blockade based on nonlinear effects
Han-Qiu Zhang, Shuang-Shuo Chu, Jian-Song Zhang +2
We present an alternative scheme to achieve nonreciprocal unconventional magnon blockade (NUMB) in a hybrid system formed by two microwave cavities and one yttrium iron garnet (YIG…

Simultaneous cooling of degenerate mechanical modes in unresolved sideband regime via optical and mechanical nonlinearities
Shuang-Shuo Chu, Han-Qiu Zhang, Jian-Song Zhang +3
We propose a scheme to simultaneously cool multiple degenerate mechanical modes in optomechanical systems beyond the resolved sideband regime. In general, one of the main obstacles…
