First-passage time distribution of a Brownian particle harmonically confined in a viscoelastic bath
Brandon R. Ferrer, Juan Ruben Gomez-Solano
We investigate theoretically and experimentally the first passage-time properties of a spherical Brownian particle that is harmonically trapped at thermal equilibrium in a fluid at…
Transition path time over a barrier of a colloidal particle in a viscoelastic bath
Brandon R. Ferrer, Alejandro V. Arzola, Denis Boyer +1
We experimentally study the statistics of the transition path time taken by a submicron bead to successfully traverse an energy barrier created by two optical tweezers in two proto…
Experimental measurement of mean transition path velocities of colloidal particles surmounting energy barriers
Brandon R. Ferrer, Juan Ruben Gomez-Solano
Transition paths are rare events occurring when a system, thanks to the effect of fluctuations, crosses successfully from one stable state to another by surmounting an energy barri…
Stochastic energetics of a colloidal particle trapped in a viscoelastic bath
Farshad Darabi, Brandon R. Ferrer, Juan Ruben Gomez-Solano
We investigate the statistics of the fluctuations of the energy transfer between an overdamped Brownian particle, whose motion is confined by a stationary harmonic potential, and a…
Fluid viscoelasticity triggers fast transitions of a Brownian particle in a double well optical potential
Brandon R. Ferrer, Juan Ruben Gomez-Solano, Alejandro V. Arzola
Thermally activated transitions are ubiquitous in nature, occurring in complex environments which are typically conceived as ideal viscous fluids. We report the first direct observ…
