Mutually attracting spin waves in the square-lattice quantum antiferromagnet
M. Powalski, K. P. Schmidt, G. S. Uhrig
The Heisenberg model for S=1/2 describes the interacting spins of electrons localized on lattice sites due to strong repulsion. It is the simplest strong-coupling model in condense…

Roton minimum as fingerprint of magnon-Higgs scattering in ordered quantum antiferromagnets
M. Powalski, G. S. Uhrig, K. P. Schmidt
A quantitative description of magnons in long-range ordered quantum antiferromagnets is presented which is consistent from low to high energies. It is illustrated for the generic $…
