Irreversibility in Active Matter: General Framework for Active Ornstein-Uhlenbeck Particles
Frontiers in Physics, 2021 Active matter systems are driven out of equilibrium by conversion of energy into directed motion locally on the level of the individual constituents.

Active Matter Ratchets with an External Drift
, 2013 When active matter particles such as swimming bacteria are placed in an asymmetric array of funnels, it has been shown that a ratchet effect can occur even in the absence of an external drive. Here we examine active ratchets for two dimensional arrays of

Incompressible polar active fluids in the moving phase in dimensions d > 2
New Journal of Physics, 2018 We study universal behavior in the moving (polar ordered) phase of a generic system of motile particles with alignment interactions in the incompressible limit for spatial dimensions d > 2. Using a dynamical renormalization group analysis, we obtain the

Active dynamics of tissue shear flow
New Journal of Physics, 2017 We present a hydrodynamic theory to describe shear flows in developing epithelial tissues. We introduce hydrodynamic fields corresponding to state properties of constituent cells as well as a contribution to overall tissue shear flow due to ...

The role of fluid flow in the dynamics of active nematic defects
New Journal of Physics, 2021 We adapt the Halperin–Mazenko formalism to analyze two-dimensional active nematics coupled to a generic fluid flow. The governing hydrodynamic equations lead to evolution laws for nematic topological defects and their corresponding density fields.

Confined active Brownian particles: theoretical description of propulsion-induced accumulation
New Journal of Physics, 2018 The stationary-state distribution function of confined active Brownian particles (ABPs) is analyzed by computer simulations and analytical calculations. We consider a radial harmonic as well as an anharmonic confinement potential. In the simulations, the

A minimal spatial cell lineage model of epithelium: tissue stratification and multi-stability
New Journal of Physics, 2018 A minimal model which includes spatial and cell lineage dynamics for stratified epithelia is presented. The dependence of tissue steady state on cell differentiation models, cell proliferation rate, cell differentiation rate, and other parameters are ...
