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…
Learning quantum phase transitions through Topological Data Analysis
Andrea Tirelli, Natanael C. Costa
We implement a computational pipeline based on a recent machine learning technique, namely the Topological Data Analysis (TDA), that has the capability of extracting powerful infor…
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…
