Heating and cooling are fundamentally asymmetric and evolve along distinct pathways

M Ibánez, C Dieball, A Lasanta, A Godec, RA Rica - Nature Physics, 2024 - nature.com
According to conventional wisdom, a system placed in an environment with a different
temperature tends to relax to the temperature of the latter, mediated by the flows of heat or …

Optimal control in stochastic thermodynamics

S Blaber, DA Sivak - Journal of Physics Communications, 2023 - iopscience.iop.org
We review recent progress in optimal control in stochastic thermodynamics. Theoretical
advances provide in-depth insight into minimum-dissipation control with either full or limited …

Beyond linear response: Equivalence between thermodynamic geometry and optimal transport

A Zhong, MR DeWeese - Physical Review Letters, 2024 - APS
A fundamental result of thermodynamic geometry is that the optimal, minimal-work protocol
that drives a nonequilibrium system between two thermodynamic states in the slow-driving …

Shortcuts of freely relaxing systems using equilibrium physical observables

IGA Pemartín, E Mompó, A Lasanta, V Martín-Mayor… - Physical Review Letters, 2024 - APS
Many systems, when initially placed far from equilibrium, exhibit surprising behavior in their
attempt to equilibrate. Striking examples are the Mpemba effect and the cooling-heating …

Geometric thermodynamics for the Fokker–Planck equation: stochastic thermodynamic links between information geometry and optimal transport

S Ito - Information geometry, 2024 - Springer
We propose a geometric theory of non-equilibrium thermodynamics, namely geometric
thermodynamics, using our recent developments of differential-geometric aspects of entropy …

Learning protocols for the fast and efficient control of active matter

C Casert, S Whitelam - Nature Communications, 2024 - nature.com
Exact analytic calculation shows that optimal control protocols for passive molecular systems
often involve rapid variations and discontinuities. However, similar analytic baselines are not …

Control of active Brownian particles: an exact solution

M Baldovin, D Guéry-Odelin, E Trizac - Physical Review Letters, 2023 - APS
Control of stochastic systems is a challenging open problem in statistical physics, with a

[HTML][HTML] Geometric approach to nonequilibrium hasty shortcuts

SS Chittari, Z Lu - The Journal of Chemical Physics, 2023 - pubs.aip.org
Complex and even non-monotonic responses to external control can be found in many
thermodynamic systems. In such systems, nonequilibrium shortcuts can rapidly drive the …

Resetting as a swift equilibration protocol in an anharmonic potential

R Goerlich, TD Keidar, Y Roichman - Physical Review Research, 2024 - APS
We present and characterize a method to accelerate the relaxation of a Brownian object
between two distinct equilibrium states. Instead of relying on a deterministic time-dependent …

Optimal time-entropy bounds and speed limits for Brownian thermal shortcuts

LB Pires, R Goerlich, AL da Fonseca, M Debiossac… - Physical Review Letters, 2023 - APS
By controlling the variance of the radiation pressure exerted on an optically trapped
microsphere in real time, we engineer temperature protocols that shortcut thermal relaxation …
