The study of the phase transition from first-order to second-order in the two dimensional Potts model due to random applied fields

Description

Abstract
In this paper, we study the nature of phase transition of the two-dimensional six-state Potts model under the external random magnetic field.
The six-state Potts model exist temperature-dependent first-order phase transition. When the external random field is applied, the nature of phase can be altered from first-order to second-order.By employing the Monte Carlo simulation method, we inspected the energy histogram and Binder parameter of the six-state Potts model under the external random magnetic field. According to our analyses, the evidences reveal that the phase transition does not change until the external magnetic field is greater then 0.02
