Interacting electronic topological insulators in three dimensions
Speaker(s): Senthil Todadri
Abstract: I will review recent progress in describing interacting electronic topological insulators/superconductors in three dimensions. The focus will be on Symmetry Protected Topological (SPT) phases of electronic systems with charge conservation and time reversal. I will argue that the well known Z2... read more

Interacting topological insulators in three dimensions: classification and properties
Speaker(s): Senthil Todadri
Abstract: A fundamental open problem in condensed matter physics is how the dichotomy between conventional and topological band insulators is modified in the presence of strong electron interactions. In this talk I describe recent work showing that there are 6 new electronic topological insulators... read more

3d boson topological insulators and quantum spin liquids
Speaker(s): Senthil Todadri
Abstract: I will discuss recent work on 3d Symmetry Protected Topological (SPT) phases of bosonic systems, and their implications for understanding the more exotic quantum spin liquid phases. First I will describe various characterizations of these 3d SPT phases, in particular their surface effective th... read more

Integer Quantum Hall Effect for Bosons: A Physical Realization
Speaker(s): Senthil Todadri
Abstract: A simple physical realization of an integer quantum Hall state of interacting two dimensional bosons is provided. This is an example of a "symmetry-protected topological" (SPT) phase which is a generalization of the concept of topological insulators to systems of interacting bosons or ferm... read more

How might a Fermi surface die?
Speaker(s): Senthil Todadri
Abstract: In the last many years a number of metallic solids have been studied that defy understanding within the principles of conventional textbook solid state physics. The most famous are the cuprate high temperature superconductors though many other examples have been found. In this talk I will argue that... read more
