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…
Density waves in low-pressure bilayer nickelates
Lauro B. Braz, Steffen Bötzel, Frank Lechermann +4
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…
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…
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\…
Charge and spin fluctuations in superconductors with intersublattice and interorbital interactions
Lauro B. Braz, George B. Martins, Luis G. G. V. Dias da Silva
Multiband superconductors have featured one of the main challenges to achieve a comprehensive understanding of unconventional superconductivity. Here, the multiband character is st…
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…
Superconductivity from spin fluctuations and long-range interactions in magic-angle twisted bilayer graphene
Lauro B. Braz, George B. Martins, Luis G. G. V. Dias da Silva
Magic-angle twisted bilayer graphene (MATBG) has been extensively explored both theoretically and experimentally as a suitable platform for a rich and tunable phase diagram that in…
A semi-empirical analysis of the paramagnetic susceptibility of solid state magnetic clusters
Lauro B. Braz, Fernando A. Garcia
Recent developments in the synthesis of new magnetic materials lead to the discovery of new quantum paramagnets. Many of these materials, such as the perovskites BaLnMn…
