A geometric framework for spin relaxation
Sophia N. Fricke, Kieren A. Harkins, Ashok Ajoy +1
Spin relaxation is conventionally described by two independent phenomenological rates - longitudinal () and transverse () - whose separation obscures a deeper structural…

Cryogenic field-cycling instrument for optical NMR hyperpolarization studies
Noella D'Souza, Kieren A. Harkins, Cooper Selco +10
Optical dynamic nuclear polarization (DNP) offers an attractive approach to enhancing the sensitivity of nuclear magnetic resonance (NMR) spectroscopy. Efficient, optically-generat…

Anomalously extended Floquet prethermal lifetimes and applications to long-time quantum sensing
Kieren A. Harkins, Cooper Selco, Christian Bengs +8
Floquet prethermalization is observed in periodically driven quantum many-body systems where the system avoids heating and maintains a stable, non-equilibrium state, for extended p…
