PQI2016 David Pekker: Emergent Conserved Quantities in Strongly Disordered Matter

David Pekker's (Pitt) talk is about emergent conserved quantities in strongly disordered matter.
He explains how the conventional wisdom that states that interacting systems are their own heat baths breaks down via the spontaneous appearance of local quantum numbers and describes the renormalization method he used to find them. This approach, called a Wegner flow, could be a foundation for the analytical theory of many-body localization transitions.
