Optical pulse-induced quantum geometric waves in graphene
Luis Fernando Cardenas Castillo, Wei Chen
We show that, under a short optical pulse, the quantum metric of Bloch states in the momentum-time (kx, ky , t) of graphene becomes dynamic and exhibits a wave-like behavior near D…

Quantum geometry of common semiconductors
David Porlles, Wei Chen
The quantum geometric properties of typical diamond-type (C, Si, Ge) and zincblende-type (GaAs, InP, etc) semiconductors are investigated by means of the tight-bin…

Quantum geometric origin of the Meissner effect and superfluid weight marker
David Porlles, Wei Chen
The momentum space of conventional superconductors is recently recognized to possess a quantum metric defined from the overlap of filled quasihole states at neighboring momenta. Fo…
