Exponentially faster cooling in a colloidal system
A Kumar, J Bechhoefer - Nature, 2020 - nature.com
As the temperature of a cooling object decreases as it relaxes to thermal equilibrium, it is
intuitively assumed that a hot object should take longer to cool than a warm one. Yet, some …

Driving rapidly while remaining in control: classical shortcuts from Hamiltonian to stochastic dynamics
Stochastic thermodynamics lays down a broad framework to revisit the venerable concepts
of heat, work and entropy production for individual stochastic trajectories of mesoscopic …

Fluid viscoelasticity triggers fast transitions of a Brownian particle in a double well optical potential
BR Ferrer, JR Gomez-Solano, AV Arzola - Physical Review Letters, 2021 - APS
Thermally activated transitions are ubiquitous in nature, occurring in complex environments
which are typically conceived as ideal viscous fluids. We report the first direct observations …
