报告介绍 | 内容摘要:
Topological states of matter support quasiparticle excitations with fractional charge and possibly exotic statistics of the non-Abelian type, known as non-Abelian anyons. Current experimental attempts to reveal such exotic statistics focus on interference involving edge transport. In this talk we will discuss how one can reveal the non-Abelian statistics in bulk probes. We show that bulk thermopower is a promising way to detect the non-Abelian nature, and measure the quantum dimension (a key parameter that quantifies non-Abelian statistics) of these anyons. We also demonstrate a novel cooling effect associated with them. We discuss application of these ideas to the specific candidate system of FQH liquid at filling factor 5/2, and topological insulator-superconductor hybrid systems. |
