Affinity and Diversity: Quantifying Mechanisms of Data Augmentation
Raphael Gontijo-Lopes, Sylvia J. Smullin, Ekin D. Cubuk +1
Though data augmentation has become a standard component of deep neural network training, the underlying mechanism behind the effectiveness of these techniques remains poorly under…
A new test of local Lorentz invariance using Ne-Rb-K comagnetometer
M. Smiciklas, J. M. Brown, L. W. Cheuk +1
We develop a new comagnetometer using Ne atoms with nuclear spin and Rb atoms polarized by spin-exchange with K atoms to search for tensor interactions that violate…
New limit on Lorentz and CPT-violating neutron spin interactions
J. M. Brown, S. J. Smullin, T. W. Kornack +1
We performed a search for neutron spin coupling to a Lorentz and CPT-violating background field using a magnetometer with overlapping ensembles of K and He atoms. The co-magnet…
Improved constraints on non-Newtonian forces at 10 microns
Andrew A. Geraci, Sylvia J. Smullin, David M. Weld +2
Several recent theories suggest that light moduli or particles in "large" extra dimensions could mediate macroscopic forces exceeding gravitational strength at length scales below…
A low-noise ferrite magnetic shield
T. W. Kornack, S. J. Smullin, S. -K. Lee +1
Ferrite materials provide magnetic shielding performance similar to commonly used high permeability metals but have lower intrinsic magnetic noise generated by thermal Johnson curr…
A Low-Noise High-Density Alkali Metal Scalar Magnetometer
S. J. Smullin, I. M. Savukov, G. Vasilakis +2
We present an experimental and theoretical study of a scalar atomic magnetometer using an oscillating field-driven Zeeman resonance in a high-density optically-pumped potassium vap…
