Charge fluctuations and topological phases in Kitaev-Heisenberg ladders
M. G. Sousa, O. Ãvalos-Ovando, E. Vernek +1
We investigate the stability of topological phases in doped Kitaev-Heisenberg ladders by studying the competition with itinerant electrons and the associated charge fluctuations in…

Magnetic response and antiferromagnetic correlations in strained kagome ribbons
R. F. P. Costa, E. Vernek, S. E. Ulloa
We study the physics of the strong-coupling Hubbard model in a kagome lattice ribbon under mechanical tension and half-filling. It is known that in the absence of strain, the latti…
