Nonreciprocal superradiant quantum phase transition induced by the magnon Kerr effect
Guo-Qiang Zhang, Si-Yan Lin, Wei Feng +3
Recently, proposals for realizing a nonreciprocal superradiant quantum phase transition (SQPT) have been put forward, based on either nonreciprocal interactions between two spin en…
