Arcsine Laws in Stochastic Thermodynamics
Andre C. Barato, Édgar Roldán, Ignacio A. Martínez +1
We show that the fraction of time a thermodynamic current spends above its average value follows the arcsine law, a prominent result obtained by Lévy for Brownian motion. Stochasti…
Energy transfer between colloids via critical interactions
Ignacio A. Martínez, Clemence Devailly, Artyom Petrosyan +1
We report the observation of a temperature-controlled synchronization of two Brownian-particles in a binary mixture close to the critical point of the demixing transition. The two…
Fast equilibrium switch of a micro mechanical oscillator
Anne Le Cunuder, Ignacio Martinez, Artyom Petrosyan +3
We demonstrate an accurate method to control the motion of a micromechanical oscillator in contact with a thermal bath. The experiment is carried out on the cantilever tip of an At…
Thermodynamics at the microscale: from effective heating to the Brownian Carnot engine
L. Dinis, I. A. Martínez, É. Roldán +2
We review a series of experimental studies of the thermodynamics of nonequilibrium processes at the microscale. In particular, in these experiments we studied the fluctuations of t…
Engineered swift equilibration of a Brownian particle
Ignacio Martinez, Artyom Petrosyan, David Guéry-Odelin +2
A fundamental and intrinsic property of any device or natural system is its relaxation time relax, which is the time it takes to return to equilibrium after the sudden change of a…
Brownian Carnot engine
Ignacio A. Martínez, Édgar Roldán, Luis Dinis +3
The Carnot cycle imposes a fundamental upper limit to the efficiency of a macroscopic motor operating between two thermal baths. However, this bound needs to be reinterpreted at mi…
Adiabatic processes realized with a trapped Brownian particle
Ignacio A. Martínez, Édgar Roldán, Luis Dinis +2
We experimentally realize quasistatic adiabatic processes using a single optically-trapped micro- sphere immersed in water whose effective temperature is controlled by an external…
Realization of nonequilibrium thermodynamic processes using external colored noise
Pau Mestres, Ignacio A. Martinez, Antonio Ortiz-Ambriz +2
We investigate the dynamics of single microparticles immersed in water that are driven out of equilibrium in the presence of an additional external colored noise. As a case study,…
Measuring kinetic energy changes in the mesoscale with low acquisition rates
Édgar Roldán, Ignacio A. Martínez, Luis Dinis +1
We describe a new technique to estimate the mean square velocity of a Brownian particle from time series of the position of the particle sampled at frequencies several orders of ma…
Universal features in the energetics of symmetry breaking
Edgar Roldan, Ignacio A Martinez, Juan MR Parrondo +1
A symmetry breaking (SB) involves an abrupt change in the set of microstates that a system can explore. This change has unavoidable thermodynamic implications. According to Boltzma…
