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…

Active Cahn-Hilliard theory for nonequilibrium phase separation: quantitative macroscopic predictions and a microscopic derivation
Sumeja Bureković, Filippo De Luca, Michael E. Cates +1
Phase-separating active systems can display phenomenology that is impossible in equilibrium. The binodal densities are not solely determined by a bulk (effective) free energy, but…

Eppur si muove: Shape of topological defects -- and consequent motion -- in active nematics
Giacomo Marco La Montagna, Sumeja Burekovic, Ananyo Maitra +1
Topological defects in systems with liquid-crystalline order are crucial in determining their large-scale properties. In active systems, they are known to have properties impossibl…
