Towards a Matrix Product Ansatz in Two Dimensions
Chandraniva Guha Ray, Aikya Banerjee, P. K. Mohanty
Matrix product ansatz (MPA) is a powerful framework for constructing exact steady state weights of one dimensional non-equilibrium stochastic processes; but its generalization to h…
Minority-Triggered Reorientations Yield Macroscopic Cascades and Enhanced Responsiveness in Swarms
Simon Syga, Chandraniva Guha Ray, Josué Manik Nava-Sedeño +2
Collective motion in animals and cells often exhibits rapid reorientations and scale-free velocity correlations. This allows information to spread rapidly through the group, allowi…
Control of lumen morphology by lateral and basal cell surfaces
Chandraniva Guha Ray, Markus Mukenhirn, Alf Honigmann +1
Across development, the morphology of fluid-filled lumina enclosed by epithelial tissues arises from an interplay of lumen pressure, mechanics of the cell cortex, and cell-cell adh…
How motility affects Ising transitions
Chandraniva Guha Ray, Indranil Mukherjee, P. K. Mohanty
We study a lattice gas model of hard-core particles on a square lattice experiencing nearest neighbour attraction . Each particle has an internal orientation, independent of the…
