Strong Mpemba effects in the antiferromagnetic Ising model arise from reentrant phase transitions that allow quenches to selectively avoid or excite the staggered slow relaxation mode in the paramagnetic phase.
Asymmetric well widths and barrier in a bistable potential allow finite-time bit erasure with heat below kT ln 2, bounded below by the effective free-energy change of the process.

Improving the efficiency of finite-time memory erasure with potential barrier shaping
Asymmetric well widths and barrier in a bistable potential allow finite-time bit erasure with heat below kT ln 2, bounded below by the effective free-energy change of the process.
