Description
The Mpemba effect is a counterintuitive phenomenon in which hotter substances cool down faster. This phenomenon can be observed under limited conditions. On the other hand, the quantum Mpemba effect (QME) is quantum analogue of it by replacing the temperature with other quantities. The QME may have various origins but it is helpful if we can understand its common mechanism. To shed light on it, we investigate the emergence of the QME by analyzing time evolution in the bottom-up holographic superfluid model. Our results indicate that the QME widely occurs in the holographic superfluid model under the probe limit.
