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…
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…
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…
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…
Vorticity phase separation and defect lattices in the isotropic phase of active liquid crystals
Fernando Caballero, Zhihong You, M. Cristina Marchetti
We use numerical simulations and linear stability analysis to study the dynamics of an active liquid crystal film on a substrate in the regime where the passive system would be iso…
Controlling liquid-liquid phase behavior with an active fluid
Alexandra M. Tayar, Fernando Caballero, Trevor Anderberg +3
Demixing of binary liquids is a ubiquitous transition, which is explained using a well-established thermodynamic formalism that requires equality of intensive thermodynamics parame…
Activity-suppressed phase separation
Fernando Caballero, M. Cristina Marchetti
We use a continuum model to examine the effect of activity on a phase separating mixture of an extensile active nematic and a passive fluid. We highlight the distinct role of previ…
Inference, prediction and optimization of non-pharmaceutical interventions using compartment models: the PyRoss library
R. Adhikari, Austen Bolitho, Fernando Caballero +15
PyRoss is an open-source Python library that offers an integrated platform for inference, prediction and optimisation of NPIs in age- and contact-structured epidemiological compart…
Stealth entropy production in active field theories near Ising critical points
Fernando Caballero, Michael E. Cates
We address the steady-state entropy production rate (EPR) of active scalar theories, which lack time-reversal symmetry, close to a phase-separation critical point. We conside…
From bulk to microphase separation in scalar active matter: A perturbative renormalization group analysis
Fernando Caballero, Cesare Nardini, Michael E. Cates
We consider a dynamical field theory (Active Model B+) that minimally extends the equilibrium Model B for diffusive phase separation of a scalar field, by adding leading-order term…
Strong coupling in conserved surface roughening: A new universality class?
Fernando Caballero, Cesare Nardini, Frederic van Wijland +1
The Kardar-Parisi-Zhang (KPZ) equation defines the main universality class for nonlinear growth and roughening of surfaces. But under certain conditions, a conserved KPZ equation (…
