Driving and Probing a Disordered Dipolar Spin Bath with a Nitrogen-Vacancy Center

Poster

Abstract

The hybrid NV-P1 spin system in diamond offers a controllable setting for exploring many-body dynamics in a strongly disordered, long-range interacting environment. Through a combination of optical and microwave control, NV centers can both perturb the denser P1 spin bath away from thermal equilibrium and act as a local probe of its energy landscape. Performing "pump-probe spectroscopy" in this fashion, we observe long-lived narrow features in the P1 spectrum left behind by the NV pump, suggesting intriguing connections to hole-burning behavior in glassy spin systems. These results raise important questions about energy transport and dissipation in systems of disordered quantum dipoles, which we address through a combination of analytical modelling and neural quantum state-based simulations.
