Breakdown and Restoration of Hydrodynamics in Dipole-conserving Active Fluids
Anish Chaudhuri, Lokrshi Prawar Dadhichi, Arijit Haldar
We present a general hydrodynamic theory for active fluids, capable of describing living matter, that conserve center of mass or dipole moment. Imposition of dipole or center-of-ma…

Superdiffusion and antidiffusion in an aligned active suspension
Lokrshi Prawar Dadhichi, Suvendra K. Sahoo, K. Vijay Kumar +1
We show theoretically that an imposed uniaxial anisotropy leads to new universality classes for the dynamics of active particles suspended in a viscous fluid. In the homogeneous st…

Nonmutual torques and the unimportance of motility for long-range order in two-dimensional flocks
Lokrshi Prawar Dadhichi, Jitendra Kethapelli, Rahul Chajwa +2
As the constituent particles of a flock are polar and in a driven state, their interactions must, in general, be fore-aft asymmetric and non-reciprocal. Within a model that explici…
