Ni-O hybridization as a stabilizer for superconductivity in LaNiO: a DFT+RPA study
Lauro B. Braz, Daniel D. Rivera, Emmanuel V. C. Lopes +3
The superconducting gap symmetry of high-pressure bilayer nickelates remains under debate, with weak- and strong-coupling approaches yielding different pairing tendencies. In this…
Controllable Quantum Spin Hall Phases in BiTe-Family van der Waals Heterobilayers
Emmanuel V. C. Lopes, Pedro H. Sophia, Felipe Crasto de Lima +1
The tunability and control of topological edge/surface states are crucial for the development of new device applications. In this work, by combining first-principles calculations a…
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…
Physical Pictures for Quasisymmetry in Crystals
Bryan D. Assunção, Emmanuel V. C. Lopes, Tome M. Schmidt +1
Quasisymmetry (QS) provides a novel route to understand and control near-degeneracies, Berry curvature, optical selection rules, and symmetry-protected phenomena in quantum materia…
Weyl semimetal engineering by symmetry control in NiTe
Marcos G. O. Junior, Augusto L. Araújo, Emmanuel V. C. Lopes +1
In this work, we investigate the emergence of Weyl points in an inversion symmetry-breaking 1T-NiTe system. Through first-principles calculations based on the density functiona…
