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 ...

Phase diagram study of a dimerized spin-S zig–zag ladder
(IOP Publishing, 2014-07)
The phase diagram of a frustrated spin-S zig–zag ladder is studied through different numerical and analytical methods. We show that for arbitrary S, there is a family of Hamiltonians for which a fully-dimerized state is ...

Current jumps in flat-band ladders with Dzyaloshinskii-Moriya interactions
(American Physical Society, 2020-11-20)
Localized magnons states, due to flat bands in the spectrum, is an intensely studied phenomenon and can be found in many frustrated magnets of different spatial dimensionality. The presence of Dzyaloshinskii-Moriya (DM) ...
Disorder effects in the S1⁄41 antiferromagnetic spin ladder CaV2O4
(Elsevier Science, 2015-05-11)
We study the physical properties of the antiferromagnetic spin ladder CaV2O4 (CVO) and the Y-doped related compound Ca0.9Y0.1V2O4. In the latter, X-ray diffraction demonstrates the segregation of a small amount of a ...
