Real space quantum metric of solids
Lucas A. Oliveira, Wei Chen
By applying the projector to the filled lattice eigenstates on a specific position, or applying the local electron annihilation operator on the many-body ground state, one can cons…
Quantum geometrical properties of topological materials
Wei Chen
The momentum space of topological insulators and topological superconductors is equipped with a quantum metric defined from the overlap of neighboring valence band states or quasih…
Detecting the spread of valence band Wannier functions by optical sum rules
Luis F. Cárdenas-Castillo, Shuai Zhang, Denis Kochan +2
The spread of valence band Wannier functions in semiconductors and insulators is a characteristic property that gives a rough estimation of how insulating is the material. We elabo…
Berry curvature and quantum metric in copper-substituted lead phosphate apatite
Wei Chen
The recent discovery of copper-substituted lead phosphate apatite, also known as LK-99, has caught much attention owing to certain experimental evidence of room-temperature superco…
