Experimental verification of a modified fluctuation-dissipation relation for a micron-sized particle in a non-equilibrium steady state
Juan Ruben Gomez-Solano, Artyom Petrosyan, Sergio Ciliberto +2
A modified fluctuation-dissipation-theorem (MFDT) for a non-equilibrium steady state (NESS) is experimentally checked by studying the position fluctuations of a colloidal particle…
Work fluctuations in a nematic liquid crystal
Sylvain Joubaud, Guillaume Huillard, Artyom Petrosyan +1
The orientation fluctuations of the director of a liquid crystal are measured, by a sensitive polarization interferometer, close to the Fréedericksz transition, which is a second o…
Aging and effective temperatures near a critical point
Sylvain Joubaud, Baptiste Percier, Artem Petrosyan +1
The orientation fluctuations of the director of a liquid crystal(LC) are measured after a quench near the Fréedericksz transition, which is a second order transition driven by an e…
Work and dissipation fluctuations near the stochastic resonance of a colloidal particle
Pierre Jop, Sergio Ciliberto, Artem Petrosyan
We study experimentally the fluctuations of the injected and dissipated energy in a system of a colloidal particle trapped in a double well potential periodically modulated by an e…
Quantum Dot Version of Berry's Phase: Half-Integer Orbital Angular Momenta
V. D. Mur, N. B. Narozhny, A. N. Petrosyan +1
We show that Berry's geometrical (topological) phase for circular quantum dots with an odd number of electrons is equal to πand that eigenvalues of the orbital angular momentum run…
Dynamical Casimir Effect in a one-dimensional uniformly contracting cavity
A. M. Fedotov, Yu. E. Lozovik, N. B. Narozhny +1
We consider particle creation (the Dynamical Casimir effect) in a uniformly contracting ideal one-dimensional cavity non-perturbatively. The exact expression for the energy spectru…
