Bias induced drift and trapping on random combs and the Bethe lattice: Fluctuation regime and first order phase transitions
Jesal D. Kotak, Mustansir Barma
We study the competition between field-induced transport and trapping in a disordered medium by studying biased random walks on random combs and the bond-diluted Bethe lattice abov…

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 $…
