Coupling 4H-Silicon Carbide spins to a microwave resonator at milli-Kelvin temperature
Ali Fawaz, Jeremy Bourhill, Stefania Castelletto +6
Coupling microwave cavity modes with spin qubit transitions is crucial for enabling efficient qubit readout and control, long-distance qubit coupling, quantum memory implementation…
Cryogenic Microwave Whispering Gallery Mode Spectroscopy of Paramagnetic Impurities in High-Purity Crystalline LiF
Steven Samuels, William Campbell, Michael E. Tobar +1
A low-noise cryogenic microwave spectroscopy experiment was performed on a high-purity lithium fluoride (LiF) crystal. The spectroscopy data revealed avoided level crossing interac…
Upconversion of Phonon Modes into Microwave Photons in a Lithium Niobate Bulk Acoustic Wave Resonator Coupled to a Microwave Cavity
S. Parashar, W. M. Campbell, J. Bourhill +3
The coupling between acoustic vibrations in a lithium niobate bulk acoustic wave resonator and microwave photons of a re-entrant microwave cavity was investigated at a temperature…
Precision Multi-Mode Microwave Spectroscopy of Paramagnetic and Rare-Earth Ion Spin Defects in Single Crystal Calcium Tungstate
Elrina Hartman, Michael E Tobar, Ben T McAllister +2
We present experimental observations of dilute ion spin ensemble defects in a low-loss single crystal cylindrical sample of CaWO cooled to mK in temperature. Crystal field…
Scalar Gravitational Aharonov-Bohm Effect: Generalization of the Gravitational Redshift
Michael E Tobar, Michael T Hatzon, Graeme R Flower +1
The Aharonov-Bohm effect is a quantum mechanical phenomenon that demonstrates how potentials can have observable effects even when the classical fields associated with those potent…
