Intrinsic spin-orbit coupling in graphene stacks
Guillermo Parra-Martinez, Alejandro Jimeno-Pozo, Ady Stern +2
The effect of spin-orbit coupling (SOC) in monolayer graphene has been thoroughly studied in the past. Its impact is commonly disregarded since the electronic structure of graphene…
Nematic and partially polarized phases in rhombohedral graphene with varying number of layers: An extensive Hartree-Fock Study
Guillermo Parra-Martínez, Alejandro Jimeno-Pozo, Jose Angel Silva-Guillén +1
Rhombohedral graphene systems with different number of layers feature an abundance of correlated phases and superconducting states in experimental measurements with different dopin…
Interaction-driven charge textures and unconventional superconductivity in strained monolayer graphene
Elias Andrade, Alejandro Jimeno-Pozo, Pierre A. Pantaleon +2
Two-dimensional systems with flat bands support correlated phases such as superconductivity. While twisted moiré systems, like twisted bilayer graphene, have revealed such states,…
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…
Influence of carrier density and disorder on the Quantum Hall plateau widths in epitaxial graphene
Ignacio Figueruelo-Campanero, Yuriko Baba, Alejandro Jimeno-Pozo +9
Since its discovery, graphene has been one of the most prominent 2D materials due to its unique properties and broad range of possible applications. In particular, the half-integer…
Double-edged Role of Interactions in Superconducting Twisted Bilayer Graphene
Xueshi Gao, Alejandro Jimeno-Pozo, Pierre A. Pantaleon +9
For the unconventional superconducting phases in moire materials, a critical question is the role played by electronic interactions in the formation of Cooper pairs. In twisted bil…
Evolution of Superconductivity in Twisted Graphene Multilayers
Min Long, Alejandro Jimeno-Pozo, Hector Sainz-Cruz +2
The group of moiré graphene superconductors keeps growing, and by now it contains twisted graphene multilayers and twisted double bilayers. We analyze the contribution of long rang…
Short vs. long range exchange interactions in twisted bilayer graphene
Alejandro Jimeno-Pozo, Zachary A. H. Goodwin, Pierre A. Pantaleón +6
We discuss the effect of long-range interactions within the self-consistent Hartree-Fock (HF) approximation in comparison to short-range atomic Hubbard interactions on the band str…
Charge fluctuations, phonons and superconductivity in multilayer graphene
Ziyan Li, Xueheng Kuang, Alejandro Jimeno-Pozo +4
Motivated by the recent experimental detection of superconductivity in Bernal bilayer (AB) and rhombohedral trilayer (ABC) graphene, we study the emergence of superconductivity in…
Junctions and superconducting symmetry in twisted bilayer graphene
Héctor Sainz-Cruz, Pierre A. Pantaleón, Vo Tien Phong +2
Junctions provide a wealth of information on the symmetry of the order parameter of superconductors. We analyze junctions between a scanning tunneling microscope (STM) tip and supe…
Superconductivity and correlated phases in non-twisted bilayer and trilayer graphene
Pierre A. Pantaleon, Alejandro Jimeno-Pozo, Hector Sainz-Cruz +3
Twisted bilayer graphene has a rich phase diagram, including superconductivity. Recently, an unexpected discovery has been the observation of superconductivity in non-twisted graph…
