Magnetic properties of the spiral spin liquid and surrounding phases in the square lattice XY model

Autor: Gonzalez, Matías G., Fancelli, Anna, Yan, Han, Reuther, Johannes

Spiral spin liquids possess a subextensively degenerate ground-state manifold, represented by a continuum of energy minima in reciprocal space. Since a small change of the spiral state wavevector requires a global change of the spin configuration in

The spin-$\frac12$ triangular lattice antiferromagnetic Heisenberg model has been for a long time the prototypical model of magnetic frustration. However, only very recently this model has been proposed to be realized in the Ba$_8$CoNb$_6$O$_{24}$ co
