Hysteresis in Ferromagnetic Random Field Ising Model with an Arbitrary Initial State
Prabodh Shukla, R Kharwanlang
We present exact expressions for hysteresis loops in the ferromagnetic random field Ising model in the limit of zero temperature and zero driving frequency for an arbitrary initial…

Domains and Interfaces in Random Fields
Prabodh Shukla
We analyze the energetics of domains and interfaces in the presence of quenched random fields, particularly at the lower critical dimension of the random field Ising model. The rel…
