Diffusion of interacting particles in discrete geometries
, 2013 We evaluate the self-diffusion and transport diffusion of interacting particles in a discrete geometry consisting of a linear chain of cavities, with interactions within a cavity described by a free-energy function.

Nonequilibrium Work distributions for a trapped Brownian particle in a time dependent magnetic field [PDF]
, 2007 We study the dynamics of a trapped, charged Brownian particle in presence of a time dependent magnetic field. We calculate work distributions for different time dependent protocols.

Feedback Control and Characterization of a Microcantilever Using Optical Radiation Pressure
, 2006 We describe a method for feedback-regulation of a microcantilever's response using optical radiation pressure. One laser measures the position of the cantilever and another laser applies a force that is a phase-shifted function of that position.

Equality connecting energy dissipation with violation of fluctuation-response relation [PDF]
, 2005 In systems driven away from equilibrium, the velocity correlation function and the linear response function to a small perturbation force do not satisfy the fluctuation-response relation (FRR) due to the lack of detailed balance in contrast to ...

Quantum dynamics of a vibrational mode of a membrane within an optical cavity
, 2010 Optomechanical systems are a promising candidate for the implementation of quantum interfaces for storing and redistributing quantum information. Here we focus on the case of a high-finesse optical cavity with a thin vibrating semitransparent membrane in

Effective coupling between two Brownian particles [PDF]
, 2006 We use the system-plus-reservoir approach to study the dynamics of a system composed of two independent Brownian particles. We present an extension of the well-known model of a bath of oscillators which is capable of inducing an effective coupling ...

Vacuum fluctuations and Brownian motion of a charged test particle near a reflecting boundary
, 2004 We study the Brownian motion of a charged test particle coupled to electromagnetic vacuum fluctuations near a perfectly reflecting plane boundary.

Theory of the sea ice thickness distribution
, 2015 We use concepts from statistical physics to transform the original evolution equation for the sea ice thickness distribution $g(h)$ due to Thorndike et al., (1975) into a Fokker-Planck like conservation law. The steady solution is $g(h) = {\cal N}(q) h^q

Transport Coherence in Frictional Ratchets [PDF]
, 2003 We study the phenomena of noise induced transport in frictional ratchet systems. For this we consider a Brownian particle moving in a space dependent frictional medium in the presence of external white noise fluctuations.

Diffusion of Point Defects in Two-Dimensional Colloidal Crystals
, 2001 We report the first study of the dynamics of point defects, mono and di-vacancies, in a confined 2-D colloidal crystal in real space and time using digital video microscopy.
