We find that sub-Ohmic dissipation is generated for sufficiently strong disorder, leading to suppression of Kondo screening on a finite fraction of spins, and giving rise to universal spin-liquid behavior.4 pages, minor changes included, typos correctedStrongly Correlated ElectronsDisordered Systems and Neural Networkstext
