Quantum Mpemba Effect Role Reversal

Published:Dec 31, 2025 12:59

•

1 min read

•

ArXiv

Analysis

This paper explores the quantum Mpemba effect, a phenomenon where a system evolves faster to equilibrium from a hotter initial state than from a colder one. The key contribution is the discovery of 'role reversal,' where changing system parameters can flip the relaxation order of states exhibiting the Mpemba effect. This is significant because it provides a deeper understanding of non-equilibrium quantum dynamics and the sensitivity of relaxation processes to parameter changes. The use of the Dicke model and various relaxation measures adds rigor to the analysis.

Key Takeaways

•Investigates the quantum Mpemba effect in a dissipative Dicke model.
•Identifies a criterion for the quantum Mpemba effect based on quantum coherence.
•Introduces and demonstrates 'role reversal' in the Mpemba effect, where relaxation order can be inverted by parameter changes.
•Uses different relaxation measures (differential quantum coherence, entanglement, trace distance) to analyze the effect.

Reference
