Engineering Quantum Phases in Two Dimensions via Vacancy-Induced Electronic Reconstruction
Emmanuel V. C. Lopes, Felipe Crasto de Lima, Caio Lewenkopf +1
Topological phases of matter are commonly understood as emerging either from crystalline symmetry and intrinsic spin-orbit coupling or from disorder-driven electronic renormalizati…

Unveiling the Electronic Origin of Anomalous Contact Conductance in Twisted Bilayer Graphene
Kevin J. U. Vidarte, Caio Lewenkopf, F. Crasto de Lima +3
This study theoretically investigates the contact conductance in twisted bilayer graphene (TBG), providing a theoretical explanation for recent experimental observations from scann…

Interacting Virtual Topological Phases in Defect-Rich 2D Materials
Felipe Crasto de Lima, Roberto H. Miwa, Caio Lewenkopf +1
We investigate the robustness of {\it virtual} topological states -- topological phases away from the Fermi energy -- against the electron-electron interaction and band filling. As…
