Malin Palö Forsström: The phase diagram of the Ising lattice Higgs model

Abstract:

The lattice Higgs model is a spin model on the edges of a hypercubic lattice and arises as a discretization of the Yang-Mills model interacting with a Higgs field. It can also be seen as a higher-dimensional analog of the Ising model coupled to an external field. In this talk, we survey what is known about the phase diagram of this model, and describe the related models that explain the behavior of the model in the different phases.
