A transient symmetry-breaking evolution accelerates relaxation to equilibrium or ground states in quantum systems for both real and imaginary time dynamics under U(1) symmetry.
Correlations enable the Mpemba effect in a resource theory framework but are necessary yet insufficient depending on distribution and parameters, explaining sporadic experimental observations.
In random quantum automaton ensembles, the subsystem symmetrization scale depends on the initial state's participation entropy, and the onset of U(1) entanglement asymmetry coincides with the onset of subsystem coherence.
More strongly entangled two-qubit states can lose entanglement faster than weaker ones under local amplitude damping due to excited-state population catalyzing sudden death.
Incorporating noise-induced quasiparticle correlations in the ν=1 QSSEP model yields the full-time distribution of entanglement entropy and shows the quantum Mpemba effect is extremely fine-tuned and hard to observe.
Evidence is provided for a Mpemba-type effect via time-crossing in density-based relaxation ordering for ground and excited states in an expanding Tonks-Girardeau Bose gas.
