Motility destabilizes an absorbing-state flock
Narayan Dutt Sharma, Subroto Mukerjee, Chandan Dasgupta +1
Activity, when it takes the form of motility, is generally seen to promote order in many-body systems. Here we present a one-dimensional lattice model that, in the non-motile limit…
Conservation laws and chaos propagation in a non-reciprocal classical magnet
Nisarg Bhatt, Purnendu Das, Subroto Mukerjee +1
We study a nonreciprocal generalization [EPL 60, 418 (2002)] of the classical Heisenberg spin chain, in which the exchange coupling is nonsymmetric, and show that it displays a bal…
Emergent hydrodynamics in a non-reciprocal classical isotropic magnet
Nisarg Bhatt, Subroto Mukerjee, Sriram Ramaswamy
The Hamiltonian nature of the precessional dynamics of the classical Heisenberg model leads to reciprocal interactions amongst the spins. Heisenberg spins are reciprocal in nature.…
