Abstract

Ever since the experimental discovery of graphene and topological insulators, there have been intense research activities in searching and identifying new topological phases of condensed matter. Low energy properties of these crystalline solids have deep connections to fundamental topics in high-energy physics such as Weyl fermions, Majorana fermions, the chiral anomaly, and supersymmetry. Thanks to the on-going progress in the synthesis of high-quality bulk and thin films of topological materials and improvement of the state-of-the-art spectroscopic methods, ample opportunities have emerged for exploring new fundamental physics in solid state materials. In this talk, we will discuss recent theoretical and experimental advances in Weyl semimetals, nodal-line semimetals, and topological superconductors. The observed Fermi arcs, drumhead surface states, and transport chiral anomaly suggest promising applications of these materials in electronic and spintronic devices.
