In chaotic quantum systems with conservation laws, states initially farther from equilibrium can thermalize faster than closer ones via hydrodynamic relaxation differences, realizing the quantum Mpemba effect.
Higher moments of the projected process ensemble reveal entanglement structures that distinguish chaotic from integrable dynamics more sharply than quantum dynamical or spatiotemporal entropies.
