Transverse charge density and the radius of the proton

1 code implementation25 Feb 2021 Alexander V. Gramolin, Rebecca L. Russell

Our reanalysis shows that the proton radius discrepancy cannot be explained by issues with fitting and extrapolating the A1 data to $Q^2 = 0$.

Search for axion-like dark matter with ferromagnets

no code implementations6 Mar 2020 Alexander V. Gramolin, Deniz Aybas, Dorian Johnson, Janos Adam, Alexander O. Sushkov

The detection scheme is based on a modification of Maxwell's equations in the presence of axion-like dark matter, which mixes with a static magnetic field to produce an oscillating magnetic field.
