Domain Wall Control of Topological Qubits in the Kitaev SSH Chain
Griffith Rufo, Sabrina Rufo, Heron Caldas +1
Zero energy states in one dimensional SSH Kitaev hybrid systems have emerged as promising candidates for topological qubits. In our work, we show that introducing a domain wall int…
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…
Tricritical behavior of a relativistic field theory in one dimension
Heron Caldas, A. L. Mota
The tricritical behavior in a class of one-dimensional (1D) field theories that exhibit spontaneous symmetry breaking at zero temperature and chemical potential is analyzed. In the…
Hybridization induced triplet superconductivity with
Edine Silva, R. C. Bento Ribeiro, Heron Caldas +1
The Kitaev superconducting chain is a model of spinless fermions with triplet-like superconductivity. It has raised interest since for some values of its parameters it presents a n…
The Schwinger and Chiral Schwinger Models in a Non-perturbative Spectral Regularization
L. F. Eleotério, G. A. Oliveira, E. W. Dias +2
We investigate the employment of a non-perturbative regularization scheme -- the spectral regularization, which is based on the gauge technique, previously implemented in the conte…
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…
