| Abstract: | The low-energy limit of a lattice theory with short-ranged interactions is expected to be a continuum quantum field theory. However, some exotic lattice models, such as the XY plaquette model and the models of fractons, do not admit a standard continuum limit. In this talk, we will examine these lattice models in detail and uncover exotic symmetries, anomalies and UV/IR mixing in these models. We will discuss how these properties can be captured by some peculiar continuum theories. |
