Hot water sometimes freezes faster than cold — a riddle known for centuries. Now physicists have found a quantum analog: a chain of particles relaxes faster if you first give it a slight jolt, tossing the excitation to the other end. This counterintuitive maneuver will open new ways to manage losses in quantum devices.
🎯 The classic Mpemba effect, first noticed by a schoolboy from Tanzania, remains unsolved: scientists have proposed over a dozen competing explanations.
