Active polar flock with birth and death

Mishra, Pawan Kumar; Mishra, Shradha (American Institute of Physics Inc., 2022-05)

We study a collection of self-propelled polar particles on a two-dimensional substrate with birth and death. We introduce a minimal lattice model for the system using active Ising spins, where each particle can have two ...
Ordering through learning in two-dimensional Ising spins

Sampat, Pranay Bimal; Verma, Ananya; Gupta, Riya; Mishra, Shradha (American Physical Society, 2022-11)

We study two-dimensional Ising spins, evolving through reinforcement learning using their state, action, and reward. The state of a spin is defined by whether it is in the majority or minority with its nearest neighbors. ...
