Bulk and microphase separation in chiral active systems
Sumeja Bureković, S. J. Kole, Ananyo Maitra +1
Many active particles phase-separate due to quorum-sensing interactions, and their self-propulsion mechanisms often break chiral symmetry. Using particle and continuum models, we u…
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…
Active uniaxially ordered suspensions on disordered substrates
Ananyo Maitra
Multiple experiments on active systems consider oriented active suspensions on substrates or in chambers confined along one direction. The theories of polar and apolar phases in su…
Enhanced orientational ordering induced by active yet isotropic bath
Ananyo Maitra, Raphael Voituriez
Can a bath of isotropic but active particles promote ordering of anisotropic but passive particles? In this paper, we uncover a fluctuation-driven mechanism by which this is possib…
Asymmetric exchange in flocks
Lokrshi Prawar Dadhichi, Rahul Chajwa, Ananyo Maitra +1
As the constituents of a flock are polar, one expects a fore-aft asymmetry in their interactions. We show here that the resulting antisymmetric part of the "exchange coupling" betw…
