Hydrodynamics of polar liquid crystals
William Kung, M. Cristina Marchetti, Karl Saunders
Starting from a microscopic definition of an alignment vector proportional to the polarization, we discuss the hydrodynamics of polar liquid crystals with local -symm…
Nematic and Polar order in Active Filament Solutions
A. Ahmadi, T. B. Liverpool, M. C. Marchetti
Using a microscopic model of interacting polar biofilaments and motor proteins, we characterize the phase diagram of both homogeneous and inhomogeneous states in terms of experimen…
Weak point disorder in strongly fluctuating flux-line liquids
Panayotis Benetatos, M. Cristina Marchetti
We consider the effect of weak uncorrelated quenched disorder (point defects) on a strongly fluctuating flux-line liquid. We use a hydrodynamic model which is based on mapping the…
Depinning and plasticity of driven disordered lattices
M. Cristina Marchetti
We review in these notes the dynamics of extended condensed matter systesm, such as vortex lattices in type-II superconductors and charge density waves in anisotropic metals, drive…
Models of plastic depinning of driven disordered systems
M. Cristina Marchetti
Two classes of models of driven disordered systems that exhibit history-dependent dynamics are discussed. The first class incorporates local inertia in the dynamics via nonmonotoni…
