Quantum limit cycles with continuous symmetries from coherent parametric driving: exact solutions and many-body extensions
Sihan Chen, Aashish A. Clerk
There is widespread interest in many-body quantum systems that exhibit limit-cycle or time-crystalline behaviour. An ideal quantum limit cycle would be realized using fully coheren…

Extracting information from a superradiant burst using simple measurements
Federico Belliardo, Anjun Chu, Martin Koppenhöfer +1
It is well known that superradiant decay of an ensemble of spins generates a complex non-classical state of light. Here, we consider the information content of a superradiant b…
