Topological characterization of modified Kane-Mele-Rashba models via local spin Chern marker
Sebastião dos Anjos Sousa Júnior, Marcus V. de S. Ferraz, José P. de Lima +1
In this work, we use the local spin Chern marker (LSCM) recently introduced by Baù and Marrazzo [Phys. Rev. B 110, 054203 (2024)] to analyze the topology of the ground-state elect…

Quantum percolation on Lieb Lattices
W. S. Oliveira, J. Pimentel de Lima, Raimundo R. dos Santos
We theoretically investigate the quantum percolation problem on Lieb lattices in two and three dimensions. We study the statistics of the energy levels through random matrix theory…
