The emergence of superconductivity (SC) in lattice models, such as the attractive Hubbard one, has renewed interest since the realization of cold-atom experiments. However, reducing the temperature in these experiments is a bottleneck; therefore, inv

A pandemia de COVID-19, que irrompeu globalmente no ínicio de 2020, surpreendeu o mundo e seguramente uma das área mais afetadas foi a da Educação. Universidades, escolas e até mesmo creches, entre outros, interromperam suas atividades presencia

Resumo Um cenário comum de ser observado nos cursos de ciências exatas de diversas universidades espalhadas pelo Brasil é uma sala composta, majoritariamente, por estudantes masculinos. O que observamos é uma intensa segregação por gênero nas

Over the past decades, magnetic frustration has been under intense debate due to its unusual properties. For instance, frustration in the kagome lattice suppresses long range spin correlations and it is expected to be a candidate for a spin liquid sy

The realization of antiferromagnetic (AF) correlations in ultracold fermionic atoms on an optical lattice is a significant achievement. Experiments have been carried out in one, two, and three dimensions, and have also studied anisotropic configurati

We use numerically unbiased methods to show that the one-dimensional Hubbard model with periodically distributed on-site interactions already contains the minimal ingredients to display the phenomenon of magnetoresistance; i.e., by applying an extern

The Kondo and Periodic Anderson Model (PAM) are known to provide a microscopic picture of many of the fundamental properties of heavy fermion materials and, more generally, a variety of strong correlation phenomena in $4f$ and $5f$ systems. In this p

With the purpose of investigating coexistence between magnetic order and superconductivity, we consider a model in which conduction electrons interact with each other, via an attractive Hubbard on-site coupling $U$, and with local moments on every si
