Inverse Mpemba effect demonstrated on a single trapped ion qubit

S Aharony Shapira, Y Shapira, J Markov, G Teza… - Physical Review Letters, 2024 - APS
The Mpemba effect is a counterintuitive phenomena in which a hot system reaches a cold
temperature faster than a colder system, under otherwise identical conditions. Here, we …

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 …

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 …

Eigenvalue crossing as a phase transition in relaxation dynamics

G Teza, R Yaacoby, O Raz - Physical review letters, 2023 - APS
When a system's parameter is abruptly changed, a relaxation toward the new equilibrium of
the system follows. We show that a crossing between the second and third eigenvalues of …

Time-averaging and nonergodicity of reset geometric Brownian motion with drift

D Vinod, AG Cherstvy, R Metzler, IM Sokolov - Physical Review E, 2022 - APS
How do near-bankruptcy events in the past affect the dynamics of stock-market prices in the
future? Specifically, what are the long-time properties of a time-local exponential growth of …

Landau theory for the Mpemba effect through phase transitions

R Holtzman, O Raz - Communications physics, 2022 - nature.com
The Mpemba effect describes the situation in which a hot system cools faster than an
identical copy that is initiated at a colder temperature. In many of the experimental …

Relaxation shortcuts through boundary coupling

G Teza, R Yaacoby, O Raz - Physical review letters, 2023 - APS
When a hot system cools down faster than an equivalent cold one, it exhibits the Mpemba
effect (ME). This counterintuitive phenomenon was observed in several systems including …

Hyperacceleration of quantum thermalization dynamics by bypassing long-lived coherences: An analytical treatment

F Ivander, N Anto-Sztrikacs, D Segal - Physical Review E, 2023 - APS
We develop a perturbative technique for solving Markovian quantum dissipative dynamics,
with the perturbation parameter being a small gap in the eigenspectrum. As an example, we …

Designing nonequilibrium states of quantum matter through stochastic resetting

G Perfetto, F Carollo, M Magoni, I Lesanovsky - Physical Review B, 2021 - APS
We consider closed quantum many-body systems subject to stochastic resetting. This means
that their unitary time evolution is interrupted by resets at randomly selected times. When a …

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 …
