Topotaxis of active Brownian particles
Koen Schakenraad, Linda Ravazzano, Niladri Sarkar +3
Recent experimental studies have demonstrated that cellular motion can be directed by topographical gradients, such as those resulting from spatial variations in the features of a…
Fluid pumping and active flexoelectricity can promote lumen nucleation in cell assemblies
Charlie Duclut, Niladri Sarkar, Jacques Prost +1
We discuss the physical mechanisms that promote or suppress the nucleation of a fluid-filled lumen inside a cell assembly or a tissue. We discuss lumen formation in a continuum the…
Statistical mechanics of asymmetric tethered membranes: spiral and crumpled phases
Tirthankar Banerjee, Niladri Sarkar, John Toner +1
We develop the elastic theory for inversion-asymmetric tethered membranes and use it to identify and study their possible phases. Asymmetry in a tethered membrane causes spontaneou…
