Multiple transitions in an infinite range p-spin random-crystal field Blume Capel model
Santanu Das, Sumedha
We study a -spin model with ferromagnetic coupling and quenched random-crystal fields for for spin-1 systems. We find that the model has lines of first order transitio…

Phase transitions in the Blume-Capel model with trimodal and Gaussian random fields
Soheli Mukherjee, Sumedha
We study the effect of different symmetric random field distributions: trimodal and Gaussian on the phase diagram of the infinite range Blume-Capel model. For the trimodal random f…

Phase transitions in XY models with randomly oriented crystal fields
Sumedha, M. Barma
We obtain a representation of the free energy of an XY model on a fully connected graph with spins subjected to a random crystal field of strength and with random orientation $…
