Spin polarization in the Hubbard model with Rashba spin-orbit coupling on a ladder
(American Physical Society, 2013-07)
The competition between on-site Coulomb repulsion and Rashba spin-orbit coupling (RSOC) is studied on two-leg ladders by numerical techniques. By studying persistent currents in closed rings by exact diagonalization, it ...
Ferromagnetic fluctuations in the Rashba-Hubbard model
(American Physical Society, 2020-05)
We study the occurrence and the origin of ferromagnetic fluctuations in the longitudinal spin susceptibility of the t-t′-Rashba-Hubbard model on the square lattice. The combined effect of the second-neighbor hopping t′ and ...
Mechanism for Unconventional Superconductivity in the Hole-Doped Rashba-Hubbard Model
(American Physical Society, 2018-04)
Motivated by the recent resurgence of interest in topological superconductivity, we study superconducting pairing instabilities of the hole-doped Rashba-Hubbard model on the square lattice with first- and second-neighbor ...
