WebThe book I am reading (Topological Insulators and Topological Superconductors, by B. Andrei Bernevig and Taylor L. Hughes), refers to the μ < 0, Δ = 0 case as the trivial insulating limit (page 198, bottom). I think I do understand why the μ < 0 and μ > 0 are topologically distinct. However I can't deduce why the μ < 0, Δ = 0 case

WebIt has recently been proposed that insulators with large band gap and strong spin-orbit coupling can host a new phase of quantum matter called a topological insulator [1,2].This exotic phase of matter is a subject of intense research because it is predicted to give rise to dissipationless spin currents [], quantum entanglements and novel macroscopic behavior … WebJul 20, 2024 · Topological phases stabilized by crystal symmetries have a number of distinct realizations. The first class that was theoretically proposed is composed of rotation and mirror topological crystalline insulators (TCIs) that host surface fermions protected by the projection of a bulk mirror plane or rotation axis onto a particular surface ( 1 – 3 ).
