Description

Abstract: A quantum wire with spin-orbit coupling, proximate to an s-wave superconductor, has a topological phase with a Majorana mode localized at each end of the superconducting part of the wire. If one of the Majorana modes couples to 2 or more channels of interacting electrons in the normal region an unusual type of frustration occurs, leading to a novel quantum critical point. I will discuss the properties of this critical point and prospects for observing it.
