Free coherent spinons in quantum square ice
Stefanos Kourtis, Claudio Castelnovo
We investigate the quantum dynamics of monopole-like excitations in quantum square ice, as captured by the strongly anisotropic spin-1/2 XXZ model on the checkerboard lattice. We o…

Bulk spectroscopic measurement of the topological charge of Weyl nodes with resonant x-rays
Stefanos Kourtis
We formulate a bulk spectroscopic method for direct measurement of the topological invariant of nondegenerate band crossings in Weyl semimetals. We demonstrate how polarization-res…

Universal signatures of Fermi arcs in quasiparticle interference on the surface of Weyl semimetals
Stefanos Kourtis, Jian Li, Zhijun Wang +2
Weyl semimetals constitute a newly discovered class of three-dimensional topological materials with linear touchings of valence and conduction bands in the bulk. The most striking…
