Dissipative time crystals can appear in spin systems, when the Z 2 symmetry of the
Hamiltonian is broken by the environment, and the square of total spin operator S 2 is …

A boundary time crystal is a quantum many-body system whose dynamics is governed by
the competition between coherent driving and collective dissipation. It is composed of N two …

Strong measurements usually restrict the dynamics of measured finite dimensional systems
to the Zeno subspace, where subsequent evolution is unitary due to the suppression of …

We study fluctuations in many-body quantum heat engines operating in the presence of
collective system-bath interactions. We show that collective effects in open quantum systems …

While the recently realized dissipative time crystal in a laser-pumped atom-cavity system in
the experiment of Keßler et al.[Phys. Rev. Lett. 127, 043602 (2021) PRLTAO 0031-9007 …

We explore the boundary time-crystal transition at the level of quantum trajectories which
result from continuous monitoring. This Letter is motivated by recent experiments [G. Ferioli …

We show a dissipative phase transition in a driven nonlinear quantum oscillator in which a
discrete time-translation symmetry is spontaneously broken in two different ways. The …

We investigate the consequences of introducing nonuniform initial conditions in the
dynamics of spin ensembles characterized by all-to-all interactions. Specifically, our study …

The design of realistic quantum technologies relies intricately on the understanding of open
quantum systems. Such open systems are often studied as an input–output theory, where …

Synchronization between limit cycle oscillators can arise through entrainment to an external
drive or through mutual coupling. The interplay between the two mechanisms has been …
