In U(1)-symmetric random circuits, initial states with lower stabilizer Rényi entropy generate nonstabilizerness faster than those with higher entropy, with the effect also depending on spatial charge structure and extending to SU(2) circuits and Hamiltonian dynamics.

Trapped-ion experiment reveals multi-Mpemba effect with multiple trajectory crossings, explained by a phase diagram combining SDM overlap and initial relaxation speed from the fastest decay mode.
GOE-like spectral chaos is neither necessary nor sufficient for quantum Mpemba crossings in a clean U(1)-conserving XXZ chain; the crossing is controlled by local charge-sector coherence structure instead.
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.
In a dephased long-range XXZ chain, the SU(2)-symmetric ground state relaxes universally as e^{-2t} because its overlap with slower modes vanishes, yielding a strong quantum Mpemba effect.
For 1D polynomial double-well potentials, the classical Mpemba effect is not caused by the double-well shape but by a hard wall on the shallow side (or a steeper tail), vanishing in an infinite system.

The Mpemba effect likes to hit a wall
For 1D polynomial double-well potentials, the classical Mpemba effect is not caused by the double-well shape but by a hard wall on the shallow side (or a steeper tail), vanishing in an infinite system.
