Topological Quantum Crystal
Over the past decade, topology has taken center stage in condensed matter physics and materials science. Many topological phases, such as 3D topological insulators (TI) and Weyl semimetals, have been observed. Despite tremendous progress, known topological phases have been largely confined in weakly-interacting, bulk materials under equilibrium. Our group search for topological phases in non-equilibrium states, in nanostructures and 2D materials, in broken symmetry states and in strongly correlated materials. These new topological phases will present key future directions over the next decade and expected to exhibit a wide range of fundamentally new physics such as Floquet topological phases, Majorana fermions, topological charge fractionalization, topological order and non-abelian anyons.
