Network construction of non-Abelian chiral spin liquids
Hernan B. Xavier, Claudio Chamon, Rodrigo G. Pereira
We use a network of chiral junctions to construct a family of topological chiral spin liquids in two spatial dimensions. The chiral spin liquid phase harbors SU(2) anyons, whic…
Chiral fixed point in a junction of critical spin-1 chains
Hernan B. Xavier, Rodrigo G. Pereira
Junctions of one-dimensional systems are of great interest to the development of synthetic materials that harbor topological phases. We study a junction of three gapless spin-1 cha…
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…
