Nanoscale engineering and dynamical stabilization of mesoscopic spin textures
Kieren Harkins, Christoph Fleckenstein, Noella D'Souza +16
Thermalization phenomena, while ubiquitous in quantum systems, have traditionally been viewed as obstacles to be mitigated. In this study, we demonstrate the ability, instead, to h…

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…
