Description
Strong zero modes are operators that commute with the Hamiltonian up to corrections that are exponentially small in system size, leading to robust spectral degeneracies throughout the many-body spectrum. In this talk, I will introduce the notion of exact strong zero modes, discuss their key properties and physical implications, and present evidence that they are not exceptional objects but rather a generic feature of a broad class of integrable models.
