Under certain condition s\, it takes a shorter time to cool a hot system than to cool the same sys tem initiated at a lower temperature. This phenomenon &ndash\; the &ldquo\ ;Mpemba Effect&rdquo\; &ndash\; is well known in water\, and has recently been observed in other systems as well. However\, there is no single gener ic mechanism that explains this counter-intuitive behavior. Using the theo retical framework of non-equilibrium thermodynamics\, we present a widely applicable mechanism for this effect\, derive a sufficient condition for i ts appearance in Markovian dynamics\, and predict an inverse Mpemba effect in heating: under proper conditions\, a cold system can heat up faster th an the same system initiated at a higher temperature. Our results suggest that it should be possible to observe the Mpemba effect and its inverse in a variety of systems\, where they have never been demonstrated before.
