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…
Random Field Ising Model
Prabodh Shukla
Recent work on random field Ising model is described briefly emphasizing exact solutions of the model in simple cases and their relevance in understanding equilibrium and non-equil…
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…
A quasiparticle description of the equation of state in SU(3) lattice QCD
P. Shukla
The lattice data for and based on staggered fermion formulations have been parameterized using a phenomenological equation of state for noninteracting but massive q…
Hysteretic Response of an Anti-Ferromagnetic Random-Field Ising Model in One Dimension at Zero Temperature
Prabodh Shukla, Ratnadeep Roy, Emilia Ray
We consider the hysteretic response of a one-dimensional anti-ferromagnetic random-field Ising model at zero temperature for a uniform bounded distribution of quenched random field…
