We experimentally investigate the stability of a quantum gas with repulsive interactions in an
optical one-dimensional lattice subjected to periodic driving. Excitations of the gas in the …

We pinpoint the conditions necessary for discrete time crystal (DTC) formation in fully
connected spin-cavity systems from the perspective of parametric resonance by mapping …

We propose a method to parametrically excite low frequency collective modes in an
interacting many body system using a Floquet driving at optical frequencies with a …
