Onset of spin-valley order and Stoner boundaries in twisted WSe
Lauro B. Braz, Luis G. G. V. Dias da Silva
We investigate spin-valley instabilities and their connection to the magnetically ordered states recently observed in the twisted bilayer dichalcogenide WSe at a twist an…
Density waves in low-pressure bilayer nickelates
Lauro B. Braz, Steffen Bötzel, Steffen Bötzel +5
The low-pressure phase diagram of LaNiO provides an important reference for understanding its pressure-induced high-temperature superconductivity. While the spin-densit…
Doping-dependent orbital magnetism in Chromium pnictides
Henri G. Mendonça, George B. Martins, Lauro B. Braz
We present results for the phase diagram of the parent compound LaCrAsO under electron doping using the matrix random-phase approximation. At low doping levels, the system stabiliz…
Interlayer interactions in under pressure: from to -wave superconductivity
Lauro B. Braz, George B. Martins, Luis G. G. V. Dias da Silva
We investigate the role of \emph{interlayer} interaction terms in the competition between different superconducting gap symmetries in the bilayer nickelate $\text{La}_3\text{Ni}_2\…
Competing magnetic states on the surface of multilayer ABC-stacked graphene
Lauro B. Braz, Tanay Nag, Annica M. Black-Schaffer
We study interaction-mediated magnetism on the surface of ABC-multilayer graphene driven by its zero-energy topological flat bands. Using the random-phase approximation we treat on…
