Hund’s metal regimes and orbital selective Mott transitions in three band systems
(IOP Publishing, 2019-06)
We analyze the electronic properties of interacting crystal field split three band systems. Using a rotationally invariant slave boson approach we analyze the behavior of the electronic mass renormalization as a function ...
First principles calculations and experimental study of the optical properties of Ni-doped ZnS
(IOP Publishing Ltd., 2019-12)
Zinc sulphide doped with nickel (Ni:ZnS) has many applications in different fields like materials science, electronics, optics, and other industrial applications. Experimentally, a large variety of methods have been developed ...
C–doped TiO2(B): A density functional theory characterization
(Elsevier Science, 2021-06-15)
Calculations based on the Density Functional Theory (DFT) were applied to study structural, electronic and optical properties of pure and C–doped TiO2(B) taking into account five different types of substitutional impurities. ...
Mechanism for Unconventional Superconductivity in the Hole-Doped Rashba-Hubbard Model
(American Physical Society, 2018-04)
Motivated by the recent resurgence of interest in topological superconductivity, we study superconducting pairing instabilities of the hole-doped Rashba-Hubbard model on the square lattice with first- and second-neighbor ...
Description of composite bosons in discrete models
(American Physical Society, 2019-07-08)
The understanding of the behavior of systems of identical composite bosons has progressed significantly in connection with the analysis of the entanglement between constituents and the development of coboson theory. The ...
Desarrollo y aplicación de métodos computacionales de avanzada para el cálculo de propiedades electrónicas de materiales correlacionados
(2018-03-27)
Estudiamos varios modelos paradigmáticos de materiales correlacionados usando la teoría de Campo Medio Dinámico (DMFT) bajo un tratamiento uni cado. El problema auxiliar de impureza generado en las iteraciones DMFT se ...
An elementary proof of Poincaré’s last geometric theorem
(Pontificia Universidad Católica del Perú, 2021)
U-J synergy effect for high-T c superconductors
(American Physical Society, 2005-12)
Using the renormalization group with included self-energy effects and exact diagonalization of small clusters we investigate the ground-state phase diagram of a two-dimensional extended Hubbard model with nearest-neighbor ...
Monoscopic vs. Stereoscopic Retinal Photography for Grading Diabetic Retinopathy Severity
