Phase diagram for the spin-3/2 quantum ferromagnetic Blume-Capel model in a transverse crystal field: an approximation at the mean-field level
D. C. Carvalho, J. A. Plascak
We investigate the phase diagram for the spin- ferromagnetic Blume-Capel model in a transverse crystal field using the standard mean-field approximation within the framework o…

A new effective-field technique for the ferromagnetic spin-1 Blume-Capel model in a transverse crystal field
J. Roberto Viana, Octavio D. Rodriguez Salmon, Minos A. Neto +1
A new approximating technique is developed so as to study the quantum ferromagnetic spin-1 Blume-Capel model in the presence of a transverse crystal field in the square lattice. Ou…
