Decoupling dipolar interactions in dense spin ensembles

Cleverly designed pulse sequences in NMR can decouple the strong dipolar interaction in dense solid-state spin systems. These decoupling sequences were originally designed to narrow spectral lines and improve resolution in NMR spectroscopy. The effective extension of coherence times using these sequences is also important for quantum control, simulation and sensing applications. In this work, we study the effectiveness of different dipolar decoupling sequences for a variety of uncorrelated single-spin and correlated multi-spin states in different samples. We explore the sensitivity of these sequences to different errors and examine potential error mitigation strategies.
