The cost of speed: Time-optimal thermal control of trapped Brownian particles
Miguel Ibanez, Antonio Patron-Castro, Antonio Lasanta +3
A thermal analogue of the classical brachistochrone problem, which minimizes the connection time between two equilibrium states of harmonically confined Brownian particles, has rec…
How target distributions shape optimal stochastic resetting
Gregorio GarcÃa-Valladares, Antonio Prados, Alessandro Manacorda +1
We investigate the search of a target with a given spatial distribution in a finite one-dimensional domain. The searcher follows Brownian dynamics and is always reset to its initia…
Optimal control of levitated nanoparticles through finite-stiffness confinement
Marco Baldovin, Ines Ben Yedder, Carlos A. Plata +4
Optimal control of levitated nanoparticles subjected to thermal fluctuations is a challenging problem, both theoretically and experimentally. In this Letter, we compute the time-de…
Maximum power Stirling-like heat engine with a harmonically confined Brownian particle
Irene Prieto-RodrÃguez, Antonio Prados, Carlos A. Plata
Heat engines transform thermal energy into useful work, operating in a cyclic manner. For centuries, they have played a key role in industrial and technological development. Histor…
