The overdamped Brownian dynamics of a harmonic oscillator is a paradigmatic system in non-equilibrium statistical mechanics, which reliably models relevant stochastic systems such as colloidal particles submitted to optical confinement. In this work, optimal thermal protocols are tailored to minimise the connection time between equilibrium states of overdamped d-dimensional oscillators. Application of control theory reveals that these optimal protocols are of bang-bang type, that is, the… 



Stochastic Time Evolution, Information Geometry, and the Cramér-Rao Bound

It is shown that the monotonicity of the Fisher information can be used to detect hidden variables in the system and that this minimal required time is determined by the initial preparation of the system.

Stochastic Thermodynamic Interpretation of Information Geometry.

A new link between stochastic thermodynamics and information theory well-known as information geometry is found and an information geometric inequality can be interpreted as a thermodynamic uncertainty relationship between speed and thermodynamic cost.

Optimal Control of Uniformly Heated Granular Fluids in Linear Response

A detailed analytical investigation of the optimal control of uniformly heated granular gases in the linear regime is presented, interested in minimising the connection time between the non-equilibrium steady states for two different values of the granular temperature by controlling the time dependence of the driving intensity.

Taming the Time Evolution in Overdamped Systems: Shortcuts Elaborated from Fast-Forward and Time-Reversed Protocols.

The reverse-engineering approach proposed in this Letter contains the current-rather limited-catalog of explicit protocols, but it also provides a systematic strategy to build the connection between arbitrary states with a physically admissible driving.

Geometrical aspects of entropy production in stochastic thermodynamics based on Wasserstein distance

We study a relationship between optimal transport theory and stochastic thermodynamics for the FokkerPlanck equation. We show that the lower bound on the entropy production is the action measured by

We retrospect three abstract models for heat engines which include a classic abstract model in textbook of thermal physics, a primary abstract model for finite-time heat engines, and a refined

Irreversible entropy production: From classical to quantum

Entropy production is a key quantity in any finite-time thermodynamic process. It is intimately tied with the fundamental laws of thermodynamics, embodying a tool to extend thermodynamic

Solution to the Fokker-Planck equation for slowly driven Brownian motion: Emergent geometry and a formula for the corresponding thermodynamic metric.

Considerable progress has recently been made with geometrical approaches to understanding and controlling small out-of-equilibrium systems, but a mathematically rigorous foundation for these methods

Optimizing the relaxation route with optimal control

It is shown that analogous bang-bang protocols, with a number of bangs equal to the number of relevant physical variables, give the minimum connecting time under quite general conditions.

Building an irreversible Carnot-like heat engine with an overdamped harmonic oscillator

We analyse non-equilibrium Carnot-like cycles built with a colloidal particle in a harmonic trap, which is immersed in a fluid that acts as a heat bath. Our analysis is carried out in the overdamped
