Description
It is well known that the order parameter for the 2dXY
model is zero in the thermodynamic limit, yet it remains
measurable even for macroscopic systems. Thus our
ability to observe the KT transition via changes in the
magnetization is a result of the "confinement" of the
system to finite size. We have been working on a family
of related models in one and three-dimensions
generalizable to d-dimensions) which exhibit behaviour
closely analogous to the 2dXY model. We will consider
the possibility that confinement in these models may
lead to KT type, or possibly other novel, phase
transitions.
