Spin chain network construction of chiral spin liquids
Gabriel Ferraz, Flavia B. Ramos, Reinhold Egger +1
We show that a honeycomb lattice of Heisenberg spin- chains with three-spin junction interactions allows for controlled analytical studies of chiral spin liquids (CSLs). Tunin…

Quantum XX chain with interface
D. Baeriswyl, G. Ferraz
The quantum XX chain - or rather ring - is studied as a toy model of an interface. Two transverse field patterns are used to define the interface, on the one hand a staggered field…
