Band Renormalization, Quarter Metals, and Chiral Superconductivity in Rhombohedral Tetralayer Graphene
Guillermo Parra-Martinez, Alejandro Jimeno-Pozo, Vo Tien Phong +7
Recently, exotic superconductivity emerging from a spin-and-valley-polarized metallic phase has been discovered in rhombohedral tetralayer graphene. To explain this observation, we…

Excitonic and magnetic phases in doped WTe monolayers: a Hartree-Fock approach
Guillermo Parra-MartÃnez, Daniel Muñoz-Segovia, Héctor Ochoa +1
Transport and local spectroscopy measurements have revealed that monolayers of tungsten ditelluride (-WTe) display a quantum spin Hall effect and an excitonic gap at neutr…

Electronic Structure and Kohn-Luttinger Superconductivity of Heavily-Doped Single-Layer Graphene
Saul Herrera, Guillermo Parra-Martinez, Philipp Rosenzweig +8
The existence of superconductivity (SC) in graphene appears to be established in both twisted and non-twisted multilayers. However, whether their building block, single-layer graph…
