Quantum Mpemba effect in a quantum dot with reservoirs

AK Chatterjee, S Takada, H Hayakawa - Physical Review Letters, 2023 - APS
We demonstrate the quantum Mpemba effect in a quantum dot coupled to two reservoirs,
described by the Anderson model. We show that the system temperatures starting from two …

Multiple quantum Mpemba effect: Exceptional points and oscillations

AK Chatterjee, S Takada, H Hayakawa - Physical Review A, 2024 - APS
We explore the role of exceptional points and complex eigenvalues on the occurrence of the
quantum Mpemba effect. To this end, we study a two-level driven dissipative system …

Mpemba effect in a Langevin system: Population statistics, metastability, and other exact results

A Biswas, R Rajesh, A Pal - The Journal of chemical physics, 2023 - pubs.aip.org
The Mpemba effect is a fingerprint of the anomalous relaxation phenomenon wherein an
initially hotter system equilibrates faster than an initially colder system when both are …

Mpemba effect in driven granular gases: Role of distance measures

A Biswas, VV Prasad, R Rajesh - Physical Review E, 2023 - APS
The Mpemba effect refers to the counterintuitive effect where a system which is initially
further from the final steady state equilibrates faster than an identical system that is initially …

Double Mpemba effect in the cooling of trapped colloids

I Malhotra, H Löwen - The Journal of Chemical Physics, 2024 - pubs.aip.org
The Mpemba effect describes the phenomenon that a system at hot initial temperature cools
faster than at an initial warm temperature in the same environment. Such an anomalous …

Thermal versus entropic Mpemba effect in molecular gases with nonlinear drag

A Megías, A Santos, A Prados - Physical Review E, 2022 - APS
Loosely speaking, the Mpemba effect appears when hotter systems cool sooner or, in a
more abstract way, when systems further from equilibrium relax faster. In this paper, we …

Mpemba-like effect protocol for granular gases of inelastic and rough hard disks

A Megías, A Santos - Frontiers in Physics, 2022 - frontiersin.org
We study the conditions under which a Mpemba-like effect emerges in granular gases of
inelastic and rough hard disks driven by a class of thermostats characterized by the splitting …

Mpemba meets Newton: Exploring the Mpemba and Kovacs effects in the time-delayed cooling law

A Santos - Physical Review E, 2024 - APS
Despite extensive research, the fundamental physical mechanisms underlying the Mpemba
effect, a phenomenon where a substance cools faster after initially being heated, remain …

Mpemba effect for a Brownian particle trapped in a single well potential

A Biswas, R Rajesh - Physical Review E, 2023 - APS
The Mpemba effect refers to the counterintuitive phenomenon of a hotter system
equilibrating faster than a colder system when both are quenched to the same low …

Mpemba effect on non-equilibrium active Markov chains

A Biswas, A Pal - arxiv preprint arxiv:2403.17547, 2024 - arxiv.org
We study the Mpemba effect on a non-equilibrium Markov chain that mimics the run and
tumble motion of an active particle in a discrete energy landscape. The broken detailed …
