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…
The Gor'kov and Melik-Barkhudarov correction to an imbalanced Fermi gas in the presence of impurities
Heron Caldas, S. Rufo, M. A. R. Griffith
The effects of induced interactions are calculated in both clean and dirty situations, for balanced and imbalanced Fermi gases. We investigate the effects of nonmagnetic impurities…
Enhancing long-range order in disordered two-band s-wave superconductors
Heron Caldas, S. Rufo, M. A. R. Griffith
We investigate the effects of disorder in a hybridized two-dimensional two-band s-wave superconductor model. The situation in which electronic orbitals form these bands with angula…
Multi-critical Behavior in Topological Phase Transitions
S. Rufo, Nei Lopes, Mucio A. Continentino +1
Topological phase transitions can be described by the theory of critical phenomena and identified by critical exponents that define their universality classes. This is a consequenc…
Bosonic Dirac Materials on a honeycomb antiferromagnetic Ising model
Griffith M. A. R., S. Rufo, Minos A. Neto
Motivated by the recent proposal of Bosonic Dirac materials (BDM), we revisited the Ising model on a honeycomb lattice in the presence of the longitudinal and transverse fields. We…
Finite Size Effects in Topological Quantum Phase Transitions
Mucio A. Continentino, Sabrina Rufo, Griffith M. Rufo
The interest in the topological properties of materials brings into question the problem of topological phase transitions. As a control parameter is varied, one may drive a system…
