Stress-Boundary-Memory Feedback Drives Vortical-Polar Transitions in Softly Confined Active Matter
Haosheng Wen, P. B. Sunil Kumar, Mohamed Laradji
We computationally investigate how environmental sensitivity of active matter interacts with soft confinement to shape collective dynamics. In our model, the active constituents ar…
Models for membrane curvature sensing of curvature generating proteins
T. V. Sachin Krishnan, Sovan L. Das, P. B. Sunil Kumar
The curvature sensitive localization of proteins on membranes is vital for many cell biological processes. Coarse-grained models are routinely employed to study the curvature sensi…
Asters, Spirals and Vortices in Mixtures of Motors and Microtubules: The Effects of Confining Geometries on Pattern Formation
Sumithra Sankararaman, Gautam I. Menon, P. B. Sunil Kumar
We model the effects of confinement on the stable self-organized patterns obtained in the non-equilibrium steady states of mixtures of molecular motors and microtubules. In experim…
Self-organized Pattern Formation in Motor-Microtubule Mixtures
Sumithra Sankararaman, Gautam I. Menon, P. B. Sunil Kumar
We propose and study a hydrodynamic model for pattern formation in mixtures of molecular motors and microtubules. The steady state patterns we obtain in different regimes of parame…
Kinetics of Phase Ordering in a Two-Component Fluid Membrane
P. B. Sunil Kumar, Madan Rao
We present a novel Monte Carlo simulation of the phase separation dynamics of a model fluid membrane. Such a phase segregation induces shape changes of the membrane and results in…
Imbibition: An Example of Nonconserved Cellular Automaton
P. B. Sunil Kumar, Debnarayan Jana
We report an imbibition experiment in 2D random porous media in which height - height correlation function grows with a nonuniversal exponent. We find the exponent to depend on eva…
