Optical Signatures of Band Flatness and Anisotropic Quantum Geometry in Magic-Angle Twisted Bilayer Graphene

Pok Man Chiu

We study the degree of band flatness and anisotropic quantum geometry in magic-angle twisted bilayer graphene by varying the twist angle and the lattice relaxation through optical…

$Z_{2}$ topological signatures of the optical bound on maximal Berry curvature: Application to two-dimensional time-reversal symmetric insulators

Pok Man Chiu

Unlike broken time-reversal symmetric (TRS) systems with a well-defined Chern number, directly measuring the bulk $Z_{2}$ invariant and Berry curvature (if nonzero) in topological in…
