Description
Systems with subsystem symmetries have recently emerged as an important frontier in theoretical physics. They arise in novel lattice systems, describing "fractonic" phases of matter -- a generalization of topological phases. From the formal point of view, they challenge dearly held notions about what a quantum field theory is, most notably the Wilsonian paradigm. After reviewing these recent developments we'll highlight a few recent applications: symmetry breaking, interactions, foliated field theories and spacetime subsystem symmetries.
