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…
Active fluids form system-spanning filamentary networks
Paarth Gulati, Fernando Caballero, M. Cristina Marchetti
Recent experimental realizations of liquid-liquid phase separation of active liquid crystals have offered an insight into the interaction between phase separation, ubiquitous in so…
Traveling waves at the surface of active liquid crystals
Paarth Gulati, Fernando Caballero, Itamar Kolvin +2
Active liquid crystals exert nonequilibrium stresses on their surroundings through constant consumption of energy, giving rise to dynamical steady states not present in equilibrium…
Asymmetric fluctuations and self-folding of active interfaces
Liang Zhao, Paarth Gulati, Fernando Caballero +4
We study the structure and dynamics of the interface separating a passive fluid from a microtubule-based active fluid. Turbulent-like active flows power giant interfacial fluctuati…
