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…
Topological flat band, Dirac fermions and quantum spin Hall phase in 2D Archimedean lattices
F. Crasto de Lima, Gerson J. Ferreira, R. H. Miwa
Materials with designed properties arises in a synergy between theoretical and experimental approaches. In this study we explore the set of Archimedean lattices forming a guidance…
Orbital pseudospin-momentum locking in two-dimensional chiral borophene
Felipe Crasto de Lima, Gerson J. Ferreira, Roberto H. Miwa
Recently, orbital-textures have been found in Rashba and topological insulator (TI) surface states as a result of the spin-orbit coupling (SOC). Here, we predict a orbita…
