Do Spin Glasses have Phase Transitions?

The mean field theory of spin glasses predicts that there is a sharp phase transition both in zero magnetic field and in the presence of a field (the AT line). The latter is particularly surprising because this transition to a glassy state occurs without a change of symmetry. In this talk I will use Monte Carlo simulations combined with finite-size scaling to investigate whether these transitions occur in real systems.
