Capacitive detection of the topological magnetoelectric effect

ORAL

Abstract

The topological magnetoelectric effect (TME) is a defining property of 3-dimensional Z2 topological insulators that was predicted on theoretical grounds more than a decade ago, but has still not been directly measured. Here we propose a strategy for direct measurement of the TME, and discuss the precision of the effect in real devices with charge and spin disorder.
