Tuning high-Q nonlinear dynamics in a disordered quantum magnet

The Ising magnet LiHo0.045Y0.955F4 allows experimental probes of disordered quantum dynamics. Silevitch et al. show that strongly-driven localized spin clusters form effectively decoupled two-level systems whose interactions and coherence can be tuned by external ac and dc magnetic fields.
