Opacity of graphene independent of light frequency and polarization due to the topological charge of the Dirac points
Matheus S. M. de Sousa, Wei Chen
The opacity of graphene is known to be approximately given by the fine-structure constant times . We point out the fact that the opacity is roughly independent of the freque…

Mapping quantum geometry and quantum phase transitions to real space by a fidelity marker
Matheus S. M. de Sousa, Antonio L. Cruz, Wei Chen
The quantum geometry in the momentum space of semiconductors and insulators, described by the quantum metric of the valence band Bloch state, has been an intriguing issue owing to…

Vacancy-Engineered Flat-Band Superconductivity in Holey Graphene
Matheus S. M. de Sousa, Fujun Liu, Fanyao Qu +1
A bipartite lattice with chiral symmetry is known to host zero energy flat bands if the numbers of the two sublattices are different. We demonstrate that this mechanism of producin…
