Solid friction between soft filaments
Andrew Ward, Feodor Hilitski, Walter Schwenger +5
Any macroscopic deformation of a filamentous bundle is necessarily accompanied by local sliding and/or stretching of the constituent filaments. Yet the nature of the sliding fricti…
Fluctuation theorem and large deviation function for a solvable model of a molecular motor
D. Lacoste, A. W. C. Lau, K. Mallick
We study a discrete stochastic model of a molecular motor. This discrete model can be viewed as a \emph{minimal} ratchet model. We extend our previous work on this model, by furthe…
Fluctuations and Rheology in Active Bacterial Suspensions
D. T. N. Chen, A. W. C. Lau, L. A. Hough +4
We probe non-equilibrium properties of an active bacterial bath through measurements of correlations of passive tracer particles and the response function of a driven, optically tr…
Non-equilibrium fluctuations and mechanochemical couplings of a molecular motor
A. W. C. Lau, D. Lacoste, K. Mallick
We investigate theoretically the violations of Einstein and Onsager relations, and the efficiency for a single processive motor operating far from equilibrium using an extension of…
Dynamics of bacterial flow: Emergence of spatiotemporal coherent structures
Nicholas Sambelashvili, A. W. C. Lau, David Cai
We propose a simple model of self-propelled particles to show that coherent structures, such as jets and swirls, can arise from a plausible microscopic mechanisms: (i) the elongate…
State-dependent diffusion: thermodynamic consistency and its path integral formulation
A. W. C. Lau, T. C. Lubensky
The friction coefficient of a particle can depend on its position as it does when the particle is near a wall. We formulate the dynamics of particles with such state-dependent fric…
