Condensed Matter Research Seminar Title: Weakly interacting one-dimensional topological insulators: a bosonisation approach Speaker: Sam Carr, University of Kent Time and date: C36, Tuesday 14th May, 3pm - 4PM

Abstract: I will review the classification of non-interacting topological insulators and discuss how this is expected to change when weak interactions are added. I will then go on to show how this can be seen using bosonization, a common technique in one-dimension to treat interacting models. By looking at concrete models, we see a richer variety of behaviour than one can determine using topological arguments alone.
