Numerical Evidence for Critical Behavior of the Two-Dimensional Nonequilibrium Zero-Temperature Random Field Ising Model

Abstract: We give numerical evidence that the two-dimensional nonequilibrium zero-temperature random field Ising model exhibits critical behavior. Our findings are based on the results of scaling analysis and collapsing of data, obtained in extensive simulations of systems with sizes sufficiently large to clearly display the critical behavior.

“…From the standard picture [19][20][21][22] one finds that the transition is second order, but there are few arguments in support of first order transition as well [23][24][25][26] . Recent work on 2d RFIM [27][28][29][30] also claim presence of ordered state in the system at finite disorder, but the nature of transition is not clear. In our previous work 6 , we have given an argument that for a compact domain, the energy of formation of domain in CG system also scales as L d−1 .…”

“…In 2012, Aizenmann [9] too claims existence of phase transition in 2d RFIM. Spasojevic et al [10] have also given some numerical evidences which proves the existence of phase transition in 2d nonequilibrium RFIM at T = 0. Recently, Suman and Mandal [11] have studied some aspects of nonequilibrium 2d RFIM at low temperature.…”
