Active sorting to boundaries in active nematic -- passive isotropic fluid mixtures
Saraswat Bhattacharyya, Julia M. Yeomans
We use a two-fluid model to study a confined mixture of an active nematic fluid and a passive isotropic fluid. We find that an extensile active fluid preferentially accumulates at…
Self organisation of invasive breast cancer driven by the interplay of active and passive nematic dynamics
Pablo Gottheil, Saraswat Bhattacharyya, Kolya Lettl +12
In invasive breast cancer, cell clusters of varying sizes and shapes are embedded in the fibrous extracellular matrix (ECM). Although the prevailing view attributes this structure…
Phase Ordering in Binary Mixtures of Active Nematic Fluids
Saraswat Bhattacharyya, Julia M. Yeomans
We use a continuum, two-fluid approach to study a mixture of two active nematic fluids. Even in the absence of thermodynamically-driven ordering, for mixtures of different activiti…
Viscoelastic confinement induces periodic flow reversals in active nematics
Francesco Mori, Saraswat Bhattacharyya, Julia M. Yeomans +1
We use linear stability analysis and hybrid lattice Boltzmann simulations to study the dynamical behaviour of an active nematic confined in a channel made of viscoelastic material.…
Phase Separation Driven by Active Flows
Saraswat Bhattacharyya, Julia M. Yeomans
We extend the continuum theories of active nematohydrodynamics to model a two-fluid mixture with separate velocity fields for each fluid component, coupled through a viscous drag.…
Coupling Turing stripes to active flows
Saraswat Bhattacharyya, Julia M. Yeomans
We numerically solve the active nematohydrodynamic equations of motion, coupled to a Turing reaction-diffusion model, to study the effect of active nematic flow on the stripe patte…
Universal prethermal dynamics in Heisenberg ferromagnets
Saraswat Bhattacharyya, Joaquin F. Rodriguez-Nieva, Eugene Demler
We study the universal far from equilibrium dynamics of magnons in Heisenberg ferromagnets. We show that such systems exhibit universal scaling in momentum and time of the quasipar…
