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…
Pseudo-giant number fluctuations and nematic order in microswimmer suspensions
Ismail El Korde, Dóra Bárdfalvy, Jason M. Lewis +3
Giant number fluctuations (GNFs), whereby the standard deviation in the local number of particles grows faster than , are a hall…
Active phase separation: new phenomenology from non-equilibrium physics
M. E. Cates, C. Nardini
In active systems, whose constituents have non-equilibrium dynamics at local level, fluid-fluid phase separation is widely observed. Examples include the formation of membraneless…
Random organization criticality with long-range hydrodynamic interactions
Tristan Jocteur, Cesare Nardini, Eric Bertin +1
Driven soft athermal systems may display a reversible-irreversible transition between an absorbing, arrested state and an active phase where a steady-state dynamics sets in. A para…
Interface dynamics of wet active systems
Fernando Caballero, Ananyo Maitra, Cesare Nardini
We study the roughening of interfaces in phase-separated active suspensions on substrates. At both large length and timescales, we show that the interfacial dynamics belongs to the…
Fluctuation-Induced First Order Transition to Collective Motion
David Martin, Gianmarco Spera, Hugues Chaté +4
The nature of the transition to collective motion in assemblies of aligning self-propelled particles remains a long-standing matter of debate. In this article, we focus on dry acti…
