Fluid Memory Enhances Active Beating via Back-and-Forth Motion
Subhajit Gupta, Supravat Dey
Ciliary and flagellar beating often occurs in viscoelastic fluids. The surrounding fluid strongly influences the beating dynamics. Viscoelastic effects on beating dynamics, however…
Role of activity and dissipation in achieving precise beating in cilia: Insights from the rower model
Subhajit Gupta, Debasish Chaudhuri, Supravat Dey
Cilia and flagella are micron-sized filaments that actively beat with remarkable precision in a viscous medium, driving microorganism movement and efficient flow. We study the rowe…
Role of cilia activity and surrounding viscous fluid on properties of metachronal waves
Supravat Dey, Gladys Massiera, Estelle Pitard
Large groups of active cilia collectively beat in a fluid medium as metachronal waves, essential for some microorganisms motility and for flow generation in mucociliary clearance.…
Coarsening Dynamics in the Vicsek Model of Active Matter
Nisha Katyal, Supravat Dey, Dibyendu Das +1
We study the flocking model introduced by Vicsek in the "coarsening" regime. At standard self-propulsion speeds, we find two distinct growth laws for the coupled density and veloci…
Differences in mechanical properties lead to anomalous phase separation in a model cell co-culture
Supravat Dey, Moumita Das
During the morphogenesis of tissues and tumors, cells often interact with neighbors with different mechanical properties, but the understanding of its role is lacking. We use activ…
Role of spatial heterogeneity on the collective dynamics of cilia beating in a minimal 1D model
Supravat Dey, Gladys Massiera, Estelle Pitard
Cilia are elastic hairlike protuberances of the cell membrane found in various unicellular organisms and in several tissues of most living organisms. In some tissues such as the ai…
