Probability density functions of work and heat near the stochastic resonance of a colloidal particle
Alberto Imparato, Pierre Jop, Artyom Petrosyan +1
We study experimentally and theoretically the probability density functions of the injected and dissipated energy in a system of a colloidal particle trapped in a double well poten…
Initiation of granular surface flows in a narrow channel
Pierre Jop, Yoël Forterre, Olivier Pouliquen
We experimentally investigate how a long granular pile confined in a narrow channel destabilizes when it is inclined above the angle of repose. A uniform flow then develops, which…
Comment on ''Measurement of Effective Temperatures in an Aging Colloidal Glass''
Pierre Jop, Artyom Petrosyan, Sergio Ciliberto
We measure the fluctuations of the position of a silica bead trapped by an optical tweezers during the aging of a Laponite suspension. We find that the effective temperature is equ…
