Active-to-absorbing-state phase transition in an evolving population with mutation
Niladri Sarkar
We study the active to absorbing phase transition (AAPT) in a simple two-component model system for a species and its mutant. We uncover the nontrivial critical scaling behavior an…
Phase transitions and order in two-dimensional generalized nonlinear -models
Tirthankar Banerjee, Niladri Sarkar, Abhik Basu
We study phase transitions and the nature of order in a class of classical generalized nonlinear -models (NLS) constructed by minimally coupling pure NLS with additional…
The analogue Hawking effect in rotating polygonal hydraulic jumps
Arnab K. Ray, Niladri Sarkar, Abhik Basu +1
Rotation of non-circular hydraulic jumps is a recent experimental observation that lacks a theory based on first principles. Here we furnish a basic theory of this phenomenon found…
Role of interfacial friction for flow instabilities in a thin polar ordered active fluid layer
Niladri Sarkar, Abhik Basu
We construct a generic coarse-grained dynamics of a thin inflexible planar layer of polar-ordered suspension of active particles, that is frictionally coupled to an embedding isotr…
