Ising Model under Stochastic Resetting — •Shashank Kallappara1, Parbati Saha2, Varsha Banerjee2, and Martin Weigel1 — 1Institut für Physik, TU Chemnitz, Germany — 2Department of Physics, Indian Institute of Technology Delhi, India
Stochastic resetting refers to the interruption of a system’s natural evolution by randomly returning it to a prescribed initial configuration. In this work, we investigate the effect of stochastic resetting on the Ising model and extend the results of Ref. [1] by examining how the resetting protocol modifies energetic properties of the system. In particular, we analyse the behaviour of the energy under different resetting rates and initial magnetisations. Furthermore, we study the impact of resetting in the case of conserved-order-parameter Ising model using Kawasaki dynamics, revealing qualitatively distinct behaviour compared to the nonconserved Glauber dynamics.
