Bulk and microphase separation in chiral active systems
Sumeja BurekoviÄ, S. J. Kole, Ananyo Maitra +1
The paper investigates how chirality in active particle systems influences phase separation, revealing bulk and microphase separation regimes, chiral vapor bubbles, and traveling w…
Nucleation and time-reversal symmetry breaking in nonconserved scalar field theories
Noah Ziethen, Michalis Chatzittofi, Michael E. Cates +1
Classical nucleation theory (CNT) describes the formation of a stable phase from a metastable one in terms of a single reaction coordinate that corresponds to the radius of a nucle…
Nonequilibrium nucleation theory for nonconserved fields: from active matter to population dynamics
Michalis Chatzittofi, Noah Ziethen, Cesare Nardini +1
Classical nucleation theory (CNT) describes the formation of a stable phase from a metastable one. In equilibrium systems, it quantifies the free-energy competition between a favor…
Generic nonlocal statistics of the stationary measure in conserved active systems
Filippo De Luca, Michael E. Cates, Cesare Nardini
The stationary measure of equilibrium systems with detailed balance follows a Boltzmann distribution, so that for short-ranged interactions the measure is local, meaning that dista…
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…
Active Cahn-Hilliard theory for nonequilibrium phase separation: quantitative macroscopic predictions and a microscopic derivation
Sumeja BurekoviÄ, Sumeja Bureković, Filippo De Luca +2
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…
