Phase transitions
A physical system is said to exhibit a phase transition when its
order parameter changes from zero in the disordered phase to a
nonzero value in the ordered phase. This change occurs at the
critical point. The order parameter can be a scalar function of ex-
ternal variables such as magnetic field and temperature (magnetic
transition) or a multicomponent quantity.
When the change in the order parameter is discontinuous the sys-
tem undergoes a first order transition and when it is continuous
the transition is second order.
