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…
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…
Observation of a critical prethermal discrete time crystal created by two-frequency driving
William Beatrez, Christoph Fleckenstein, Arjun Pillai +8
We report the observation of long-lived Floquet prethermal discrete time crystalline (PDTC) order in a three-dimensional position-disordered lattice of interacting dipolar-coupled…
High-Field Magnetometry with Hyperpolarized Nuclear Spins
Ozgur Sahin, Erica de Leon Sanchez, Sophie Conti +7
Quantum sensors have attracted broad interest in the quest towards sub-micronscale NMR spectroscopy. Such sensors predominantly operate at low magnetic fields. Instead, however, fo…
Rapidly enhanced spin polarization injection in an optically pumped spin ratchet
Adrisha Sarkar, Brian Blankenship, Emanuel Druga +6
Rapid injection of spin polarization into an ensemble of nuclear spins is a problem of broad interest, spanning dynamic nuclear polarization (DNP) to quantum information science. W…
Floquet prethermalization with lifetime exceeding 90s in a bulk hyperpolarized solid
William Beatrez, Otto Janes, Amala Akkiraju +9
We report the observation of long-lived Floquet prethermal states in a bulk solid composed of dipolar-coupled C nuclei in diamond at room temperature. For precessing nuclear…
Dynamical decoupling in interacting systems: applications to signal-enhanced hyperpolarized readout
A. Ajoy, R. Nirodi, A. Sarkar +13
Methods that preserve coherence broadly impact all quantum information processing and metrology applications. Dynamical decoupling methods accomplish this by protecting qubits in n…
