Realizing and manipulating topological metals and their exotic properties

Abstract

Symmetry and topology, as the two fundamentally important concepts in physics and mathematics, have not only manifested themselves in science, but also provided us with profound understanding of various natural phenomena. Recently, topological gapless systems, including Z2 topological metals/semimetals [1-3], have attracted significant research interests both theoretically and experimentally. In this talk, we will report experimental realization and manipulation of several topological semimetal bands in superconducting quantum circuits as well as the detection of exotic topological characters in these systems [4][5].
