Charge fluctuations and topological phases in Kitaev-Heisenberg ladders
M. G. Sousa, O. Ávalos-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…
Optimal array geometries for kinetic magnetism and Nagaoka polarons
N. Hernandez-Cepeda, Sergio E. Ulloa
Quantum dot (QD) platforms have enabled the direct observation of Nagaoka ferromagnetism (NFM) in small arrays and non-infinite interaction strength. However, optimizing the cluste…
Superconductivity and geometric superfluid weight of a tunable flat band system
M. A. Mojarro, Sergio E. Ulloa
We study superconductivity and superfluid weight of the two-dimensional - lattice with on-site asymmetries, hosting an isolated quasi-flat band with tunable bandw…
Majorana edge states in s-wave kagome superconductors with Rashba interaction
M. A. Mojarro, Sergio E. Ulloa
We study kagome lattices with on-site and extended spin-singlet s-wave superconducting pairing and show that the inclusion of Rashba spin-orbit (RSO) interaction allows time-revers…
