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…
