Analytical and Numerical Studies of 2D XY Models with Ring Exchange
In this thesis we take several different analytic and numerical approaches to studying the classical J-K model. This model describes an interacting many-body system of spins with continuous symmetry which interact via 2-site nearest-neighbour exchange terms and 4-site ring-exchange terms. We begin b...
