Interfacial dynamics of active microtubule nematics

ORAL

Abstract

We developed an experimental system for studying the fluctuations of a soft interface between an active and passive fluid. In our system, active microtubule bundles are entirely segregated to one phase of a separated liquid-liquid mixture. The spontaneous motion of the active phase causes large interfacial deformations, allowing us to quantify the roughening of the interface by active stresses and to study other intriguing phenomena associated with active interfaces.
