The breaking of the continuous time-translation symmetry manifests, in Markovian open
quantum systems, through the emergence of nonstationary dynamical phases. Systems that …

We investigate how symmetries and conserved quantities relate to the occurrence of the
boundary time crystal (BTC) phase in a generalized spin model with Lindblad dissipation …

We discuss the emergence of non-stationarity in open quantum many-body systems. This
leads us to the definition of dissipative time crystals which display experimentally …

We investigate the creation and control of emergent collective behavior and quantum
correlations using feedback in an emitter-waveguide system using a minimal model …

We discover unexpected connections between packing configurations and rare fluctuations
in dense systems of active particles subject to pulsation of size. Using large deviation theory …

Exploring continuous time crystals (CTCs) within the symmetric subspace of spin systems
has been a subject of intensive research in recent times. Thus far, the stability of the time …

The state of an open quantum system undergoing an adiabatic process evolves by following
the instantaneous stationary state of its time-dependent generator. This observation allows …

In this paper we study genuine multipartite correlations (GMC's) in a boundary time crystal
(BTC). Boundary time crystals are nonequilibrium quantum phases of matter in contact to an …

Boundary time crystals (BTC's) are nonequilibrium phases of matter occurring in quantum
systems in contact to an environment, for which a macroscopic fraction of the many-body …

The stability of a discrete time crystal against thermal fluctuations has been studied
numerically by solving a stochastic Landau-Lifshitz-Gilbert equation of a periodically driven …
