Title: Inverse Higgs 'Constraints’

Abstract: Take a crystal, and consider how many symmetries it breaks. The first answer that comes to mind is nine, corresponding to three translations, three rotations and three boosts. But, in what is an apparent contradiction of Goldstone's theorem,  a crystal only has three Goldstone bosons, the three phonons. One reason to explain this discrepancy is something called an inverse Higgs constraint. This talk will be loosely based on the the recent paper 2103.08923, where we discuss a rigorous approach to studying these constraints, although it will focus on the motivations and general concept involved rather then the nitty gritty details of the method.
