Published in 2022 at "Physical review letters"

DOI: 10.1103/physrevlett.130.121801

Abstract: Fundamental physical constants are determined from a collection of precision measurements of elementary particles, atoms, and molecules. This is usually done under the assumption of the standard model (SM) of particle physics. Allowing for light… read more here.

Published in 2020 at "Science Advances"

DOI: 10.1126/sciadv.abc8662

Abstract: Fundamental physical constants provide the upper bound for the speed of sound in condensed matter phases. Two dimensionless fundamental physical constants, the fine structure constant α and the proton-to-electron mass ratio mpme, are attributed a… read more here.
