Topological characterization of modified Kane-Mele-Rashba models via local spin Chern marker
Sebastião dos Anjos Sousa Júnior, Marcus V. de S. Ferraz, José P. de Lima +1
In this work, we use the local spin Chern marker (LSCM) recently introduced by Baù and Marrazzo [Phys. Rev. B 110, 054203 (2024)] to analyze the topology of the ground-state electr…
Unsupervised machine learning approaches to the -state Potts model
Andrea Tirelli, Danyella O. Carvalho, Lucas A. Oliveira +3
In this paper with study phase transitions of the -state Potts model, through a number of unsupervised machine learning techniques, namely Principal Component Analysis (PCA), $k…
Percolation on Lieb lattices
W. S. Oliveira, J. Pimentel de Lima, Natanael C. Costa +1
We study site- and bond-percolation on a class of lattices referred to as Lieb lattices. In two dimensions the Lieb lattice (LL) is also known as the decorated square lattice, or a…
The two-dimensional - Holstein model
Maykon V. Araújo, José P. de Lima, Sandro Sorella +1
The competition and interplay between charge-density wave and superconductivity have become a central subject for quasi-2D compounds. Some of these materials, such as the transitio…
The transverse field XY model on the diamond chain
Sérgio Mikael V. S. Rosa, José Pimentel de Lima, Natanael C. Costa +1
We consider the transverse field model on the frustrated diamond chain, considering anisotropic exchange parameters between nearest-neighbor spins. To this end, we emp…
Superconducting Kondo phase in an orbitally-separated bilayer
Sebastião dos Anjos Sousa-Júnior, José P. de Lima, Natanael C. Costa +1
The nature of superconductivity in heavy-fermion materials is a subject under intense debate, and controlling this many-body state is central for its eventual understanding. Here,…
A mean-field approach to Kondo-attractive-Hubbard model
N. C. Costa, J. P. Lima, T. C. L. Paiva +2
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 attra…
Spiral magnetic phases on the Kondo Lattice Model: A Hartree-Fock approach
Natanael de Carvalho Costa, José Pimentel de Lima, Raimundo R. dos Santos
We study the Kondo Lattice Model (KLM) on a square lattice through a Hartree-Fock approximation in which the local spins are treated semi-classically, in the sense that their avera…
