Phonon attenuation in Z2 quantum spin liquids — •Johannes Lang1, Francesco Piazza1, Roderich Moessner1, and Matthias Punk21Max-Planck Institut für Physik komplexer Systeme, Dresden, Deutschland — 2Ludwig-Maximilians-Universität München, München, Deutschland

In Z2 quantum spin liquids low lying excitations in the form of visons can couple to lattice vibrations. The high degree of frustration in the spin lattice results in an enlarged unit cell for the visons, which in turn has characteristic signatures in phonon attenuation.
