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…
Emergence of oscillatory states of self-propelled colloids under optical confinement
Farshad Darabi, Juan Ruben Gomez-Solano
We investigate experimentally the single-particle motion in water of silica colloidal beads half-coated with carbon under the action of a converging laser beam. The beads are self-…
A stochastic Stirling engine powered by an active particle
Erick Efrain Cote-Valencia, Juan Ruben Gomez-Solano
We investigate a model of a stochastic engine operating cyclically at constant bath temperature, which consists of an overdamped Brownian harmonic oscillator that plays the role of…
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…
Energy fluctuations of a Brownian particle freely moving in a liquid
Juan Ruben Gomez-Solano
We study the statistical properties of the variation of the kinetic energy of a spherical Brownian particle that freely moves in an incompressible fluid at constant temperature. Ba…
