On Spin Glass and Its Magnetism Dynamics

Spin glasses are complex and disordered magnetic systems that have attracted considerable attention from physicists, mathematicians, and computer scientists over the past few decades. Despite extensive research, many unanswered questions remain about the nature of spin glass systems and their behavior under a magnetic field. Numerically simulating the magnetism dynamics of spin glass models will give us more insights about spin glass systems, rather than waiting for infinite time for the system to equilibrate. In our research we have used a 2D Edward-Anderson Ising spin glass system and on top of the system we have kept ferromagnetic blocks to create locally applied magnetic fields that affect the magnetism dynamics of spin glass local moments. Using numerical simulation employing the Kinetic Monte Carlo sampling method, which helps us sample the rarer events to overcome the longer relaxation time problem, we try to understand how the magnetism dynamics of spin glass is affected by the arrangement and intensity of the locally applied magnetic field.
