Mean field solution of the general spin Blume-Capel model
We study the mean field solution of the general Blume-Capel model with integer and semi-integer spins. For integer spins there exist one tricritical point and a disordered phase at low temperatures which are not present for semi-integer spins. In both cases we find, at T=0, a multiphase point in whi...

Summary: | We study the mean field solution of the general Blume-Capel model with integer and semi-integer spins. For integer spins there exist one tricritical point and a disordered phase at low temperatures which are not present for semi-integer spins. In both cases we find, at
T=0, a multiphase point in which the different phases spread out when the temperature is increased. This fact gives origin to first-order transition lines between different ordered phases (characterized by different values of the magnetizations) each one terminating at an isolated critical point. |
