Revisiting the machine-learning density functional for the one-dimensional Hubbard model with random external potential
Octavio D. R. Salmon, Minos A. Neto, J. Roberto Viana +1
We revisit the machine-learning (ML) approach to the universal density functional of the one-dimensional Hubbard model with a site-dependent random potential $\math…
Superconductivity in strongly correlated systems for local repulsive interactions
Humberto M. Silva, Francisco Dinola Neto, Griffith M. A. R. +4
The understanding of the mechanisms responsible for superconductivity in strongly correlated systems is an interesting and important subject in condensed matter physics. Several th…
Resolution of the Two-Dimensional Ferromagnetic Spin-3/2 Ising Model via Cluster Growth
J. Roberto Viana, Octavio D. Rodriguez Salmon, Minos A. Neto +2
We propose a computational methodology based on a hierarchical cluster growth process to solve spin-3/2 Ising models efficiently. The method circumvents the exponential complexity…
Effect of carbon nanotube on ballistic conduction through single-quantum-dot
Thiago Lobo, Minos A. Neto, Marcio G. da Silva +1
We will study the competitive effect between the transport of a quantum dot adsorbed to a ballistic channel and laterally coupled to a single-walled carbon nanotube (SWNT). We will…
Revisiting a variational study of the quantum spin-1/2 Heisenberg antiferromagnet
Kevin J. Urcia Vidarte, Luigui A. Chero Nunura, Octavio D. Rodriguez Salmon +1
The variational study of the ground state of the spin anisotropic Heisenberg antiferromagnet has been revisited on a square lattice by improving and correcting past numerical…
Phase transition induced for external field in tree-dimensional isotropic Heisenberg antiferromagnet
Minos A. Neto, J. Roberto Viana, Octavio D. R. Salmon +2
In this paper, we report mean-field and effective-field renormalization group calculations on the isotropic Heisenberg antiferromagnetic model under a longitudinal magnetic field.…
