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…

Room-temperature quantum sensing with photoexcited triplet electrons in organic crystals
Harpreet Singh, Noella D'Souza, Keyuan Zhong +6
Quantum sensors have notably advanced high-sensitivity magnetic field detection. Here, we report quantum sensors constructed from polarized spin-triplet electrons in photoexcited o…

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…
