Hierarchical time crystals
Jan Carlo Schumann, Igor Lesanovsky, Parvinder Solanki
Spontaneous symmetry breaking is one of the central organizing principles in physics. Time crystals have emerged as an exotic phase of matter, spontaneously breaking the time trans…
Universal relaxation speedup in open quantum systems through transient conditional and unconditional resetting
Parvinder Solanki, Igor Lesanovsky, Gabriele Perfetto
Speeding up the relaxation dynamics of many-body quantum systems is important in a variety of contexts, including quantum computation and state preparation. We demonstrate that suc…
Nonanaliticities and ergodicity breaking in noninteracting many-body dynamics via stochastic resetting and global measurements
David Soldner, Igor Lesanovsky, Gabriele Perfetto
Stochastic resetting generates nonequilibrium steady states by interspersing unitary quantum dynamics with resets at random times. When the state to which the system is reset is ch…
Training the classification capability of large-scale quantum cellular automata
Mario Boneberg, Simon Kochsiek, Gabriele Perfetto +1
In the vicinity of a phase transition ergodicity can be broken. Here, different initial many-body configurations evolve towards one of several fixed points, which are macroscopical…
