Quantum many-body scars and weak breaking of ergodicity
Thermalization is the inevitable fate of many complex quantum systems, whose dynamics
allow them to fully explore the vast configuration space regardless of the initial state—the …

Measurement-induced phase transitions in the dynamics of entanglement
We define dynamical universality classes for many-body systems whose unitary evolution is
punctuated by projective measurements. In cases where such measurements occur …

Bridging entanglement dynamics and chaos in semiclassical systems
It is widely recognized that entanglement generation and dynamical chaos are intimately
related in semiclassical models via the process of decoherence. In this paper, we propose a …

Slow quantum thermalization and many-body revivals from mixed phase space
The relaxation of few-body quantum systems can strongly depend on the initial state when
the system's semiclassical phase space is mixed; ie, regions of chaotic motion coexist with …
