In a new Nature Communications study, scientists have demonstrated the quantum version of the strong Mpemba effect (sME) in a ...

The Mpemba effect is an intriguing physical phenomenon that causes some systems to cool faster when they are hot than when ...

Does hot water really freeze faster than cold? Jennifer Ouellette describes what could be a new theoretical understanding for the so-called Mpemba effect – and why it predicts that cold water could ...

Recent advances have significantly deepened our understanding of how systems evolve when driven far from equilibrium. Non-equilibrium thermodynamics examines energy flows, dissipation and entropy ...

The question I have is - under which conditions would you say that the experiment shows the reasoning wrong, instead of experiment itself having been 'done wrong'? For example - if you do something as ...

Two cool(ing) cats: Two systems of quantum dots connected to a heat bath (represented here by cats), one with a current flowing and the other in an equilibrium state, experience a "crossing" as the ...

The Mpemba effect, in which hot systems cool faster than cold ones under the same conditions, was first described by Aristotle more than 2,000 years ago. In 1963 it was rediscovered by Tanzanian ...

Decades after a Tanzanian teenager initiated study of the “Mpemba effect,” the effort to confirm or refute it is leading physicists toward new theories about how substances relax to equilibrium. It ...

It sounds like one of the easiest experiments possible: Take two cups of water: one hot, one cold. Place both in a freezer and note which one freezes first. Common sense suggests that the colder water ...
