• Abstract: The Mpemba effect, a counterintuitive thermodynamic phenomenon in which a hotter system cools more rapidly than a colder one, has been observed in both classical and quantum systems. However, its fundamental mechanisms remain inadequately understood. In this letter, we investigate the role of classical and quantum correlations in driving anomalous relaxation behaviors within the framework of quantum resource theories. Through an analysis of multi-qubit systems in local thermal equilibrium, we establish that classical correlations alone can give rise to the Mpemba effect, while quantum correlations become relevant under specific energy degeneracy conditions. Furthermore, we demonstrate that non-Markovian memory effects and Hilbert space dimensionality play a crucial role in determining the temperature range over which this effect manifests. Finally, we discuss the possibility that the original anomalous cooling behavior observed in water may also arise from classical or quantum correlations, offering new insights into the underlying mechanisms of the phenomena collectively referred to as the Mpemba effect.

  The Mpemba effect, where a hotter system can equilibrate faster than a cooler one, has long been a subject of fascination in classical physics. We provide a concise overview of the Mpemba effect in quantum systems, with a focus on both open and isolated dynamics. Particular attention is given to the role of quantum fluctuations, integrability, and symmetry in shaping equilibration pathways.

  thermodynamic and kinetic uncertainty relations indicate trade-offs between the relative fluctuation of observables and thermodynamic quantities. We derive finite-time lower bounds on the relative fluctuation of both dynamical observables and their first passage times for arbitrary initial states. We find that the product of the relative fluctuation and entropy production or dynamical activity is enhanced by quantum coherence in a generic class of dissipative processes of systems with nondegenerate energy levels.
