Active Solids: Topological Defect Self-Propulsion Without Flow
Fridtjof Brauns, Myles O'Leary, Arthur Hernandez +2
The self-propulsion of +1/2 topological defects is a hallmark of active nematic fluids, where the defects are advected by the flow field they themselves generate. In this paper we…
Defect unbinding in active nematics
Suraj Shankar, Sriram Ramaswamy, M. Cristina Marchetti +1
We formulate the statistical dynamics of topological defects in the active nematic phase, formed in two dimensions by a collection of self-driven particles on a substrate. An impor…
Hidden entropy production and work fluctuations in an ideal active gas
Suraj Shankar, M. Cristina Marchetti
Collections of self-propelled particles that move persistently by continuously consuming free energy are a paradigmatic example of active matter. In these systems, unlike Brownian…
Poisson-Bracket Approach to the Dynamics of Bent-Core Molecules
William Kung, M. Cristina Marchetti
We generalize our previous work on the phase stability and hydrodynamic of polar liquid crystals possessing local uniaxial -symmetry to biaxial systems exhibiting loc…
Plasticity in current-driven vortex lattices
Panayotis Benetatos, M. Cristina Marchetti
We present a theoretical analysis of recent experiments on current-driven vortex dynamics in the Corbino disk geometry. This geometry introduces controlled spatial gradients in the…
