Apparent bistability from weak long-range interactions
Achilleas Lazarides, Andrea Pizzi
Bistability, or the coexistence of two stable phases, can be broken by a bias field destabilising one of the phases via the nucleation and growth of defects. Strong long-range…
Constrained Dynamics and Directed Percolation
Aydin Deger, Achilleas Lazarides, Sthitadhi Roy
In a recent work [A. Deger et al., Phys. Rev. Lett. 129, 160601 (2022)] we have shown that kinetic constraints can completely arrest many-body chaos in the dynamics of a classical,…
Arresting classical many-body chaos by kinetic constraints
Aydin Deger, Sthitadhi Roy, Achilleas Lazarides
We investigate the effect of kinetic constraints on classical many-body chaos in a translationally-invariant Heisenberg spin chain using a classical counterpart of the out-of-time-…
Classical Stochastic Discrete Time Crystals
F. M. Gambetta, F. Carollo, A. Lazarides +2
We describe a possible general and simple paradigm in a classical thermal setting for discrete time crystals (DTCs), systems with stable dynamics which is subharmonic to the drivin…
On time crystallinity in dissipative Floquet systems
Achilleas Lazarides, Sthitadhi Roy, Francesco Piazza +1
We investigate the conditions under which periodically driven quantum systems subject to dissipation exhibit a stable subharmonic response. Noting that coupling to a bath introduce…
Dynamical potentials for non-equilibrium quantum many-body phases
Sthitadhi Roy, Achilleas Lazarides, Markus Heyl +1
Out of equilibrium phases of matter exhibiting order in individual eigenstates, such as many-body localised spin glasses and discrete time crystals, can be characterised by inheren…
