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 $…
Rejection-free cluster Wang-Landau algorithm for hard-core lattice gases
Asweel Ahmed A. Jaleel, Jetin E. Thomas, Dipanjan Mandal +2
We introduce a rejection-free, flat histogram, cluster algorithm to determine the density of states of hard-core lattice gases. We show that the algorithm is able to efficiently sa…
Phase diagram of the repulsive Blume-Emery-Griffiths model in the presence of external magnetic field on a complete graph
Soheli Mukherjee, Raj Kumar Sadhu, Sumedha
For the repulsive Blume-Emery-Griffiths model the phase diagram in the space of three fields, temperature (T), crystal field (), and magnetic field (H), is computed on a complet…
Emergence of a bicritical end point in the random crystal field Blume-Capel model
Sumedha, Soheli Mukherjee
We obtain the phase diagram for the Blume-Capel model with bimodal distribution for random crystal fields, in the space of three fields: temperature, crystal field and magnetic fie…
