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…

Saturation Field as a Direct Probe of Exchange and Single-Ion Anisotropies in Spin-1 Magnets
M. A. R. Griffith, S. Rufo, H. Caldas +3
High magnetic fields provide a direct route to probe the anisotropies that govern spin dynamics in layered magnets. Using the SU(3) bond operator framework for spin 1 systems, we d…
