Translation-Invariant Parent Hamiltonians of Valence Bond Crystals
Daniel Huerga, Andres Greco, Claudio Gazza +1
We present a general method to construct translation-invariant and SU(2) symmetric antiferromagnetic parent Hamiltonians of valence bond crystals (VBC). The method is based on a ca…
Topological quantum phase transition in strongly correlated Kondo insulators in 1D
Franco T. Lisandrini, Alejandro M. Lobos, Ariel O. Dobry +1
We investigate, by means of a field-theory analysis combined with the density-matrix renormalization group (DMRG) method, a theoretical model for a strongly correlated quantum syst…
Helical currents in metallic Rashba strips
Ignacio J. Hamad, Claudio J. Gazza, Jose A. Riera
We study the texture of helical currents in metallic planar strips in the presence of Rashba spin-orbit coupling (RSOC) on the lattice at zero temperature. In the noninteracting ca…
