Time crystals are nonequilibrium many-body phases in which the state of the system
dynamically approaches a limit cycle. While these phases have recently been the focus of …

Vorticity in polariton systems has been traditionally investigated within the semiclassical
mean-field approach. In this work, we show that the fully quantized picture describes richer …

We theoretically investigate the effect of phase fluctuations on correlated photons resulting
from nondegenerate three-level atoms under the cavity radiation. The photon statistics …
