Vertex stability and topological transitions in vertex models of foams and epithelia
Meryl A. Spencer, Zahera Jabeen, David K. Lubensky
In computer simulations of dry foams and of epithelial tissues, vertex models are often used to describe the shape and motion of individual cells. Although these models have been w…
Energy decay in three-dimensional freely cooling granular gas
Sudhir N. Pathak, Zahera Jabeen, Dibyendu Das +1
The kinetic energy of a freely cooling granular gas decreases as a power law at large times . Two theoretical conjectures exist for the exponent . One based on balli…
Shock Propagation in Granular Flow Subjected to an External Impact
Sudhir N. Pathak, Zahera Jabeen, Purusattam Ray +1
We analyze a recent experiment [Phys. Rev. Lett., {\bf103}, 224501 (2009)] in which the shock, created by the impact of a steel ball on a flowing monolayer of glass beads, is quant…
Phase and frequency entrainment in locally coupled phase oscillators with repulsive interactions
Michael Giver, Zahera Jabeen, Bulbul Chakraborty
Recent experiments in one and two-dimensional microfluidic arrays of droplets containing Belousov -Zhabotinsky reactants show a rich variety of spatial patterns [J. Phys. Chem. Let…
Universal scaling dynamics in a perturbed granular gas
Zahera Jabeen, R. Rajesh, Purusattam Ray
We study the response of a granular system at rest to an instantaneous input of energy in a localised region. We present scaling arguments that show that, in dimensions, the ra…
The dynamical origin of the universality classes of spatiotemporal intermittency
Zahera Jabeen, Neelima Gupte
Studies of the phase diagram of the coupled sine circle map lattice have identified the presence of two distinct universality classes of spatiotemporal intermittency viz. spatiotem…
