Fractons from a liquid of singlet pairs
Hernan B. Xavier, Rodrigo G. Pereira
Fracton phases of matter feature a variety of exciting phenomena stemming from the restricted mobility of their quasiparticles. Here we consider a model of interacting electrons in…

Stable and Metastable Kinetic Ferromagnetism on a Ring
Ilya Ivantsov, Hernan B. Xavier, Alvaro Ferraz +1
Performing an exact diagonalization of the effective spin problem, a ferromagnetic ground state of kinetic origin is shown to emerge in a system of strongly correlated electron…

Onset of ferromagnetism for strongly correlated electrons in one-dimensional chains
Hernan B Xavier, Evgenii Kochetov, Alvaro Ferraz
The existence of the Nagaoka ferromagnetism is examined in the context of the one-dimensional Hubbard model. We construct the exact quantum partition function to describ…
