ALT An illustration on the left is labeled resource theories and a graph on the right is labeled Mpemba effect. Inside of the illustration are icons labeled athermality, asymmetry, non-stationarity, and quantum coherence. It depicts how, in a resource-theoretic framework, the Mpemba effect occurs when a state that initially possesses more of a given resource depletes that resource faster than a less resourceful state, under the evolution by the same free operation, so that their resource monotones cross. An arrow points from the illustration to a graph with time on the x axis and resourcefulness on the y axis. A solid line is labeled p̂1 and a dashed line p̂2. The intersection of the lines is labeled Tc.
