Slow dynamics of Ising models with energy barriers

Abstract

The dynamics of a three-dimensional Ising model was analyzed using the Monte Carlo simulations. The Ising model was studied for nearest-, next-nearest-, and four-spin interactions. The growth of energy barriers lowered the dynamics of the system. The characteristic features of ordinary glass were revealed by the systems with four-spin interactions. Under the conditions of strongly degenerated interaction constants, the simulation results reported the existence of slow-dynamic regime upto the melting transition zone. The Ising models four-spin domain walls were tensionless in the glassy transition phase.
