Generalized King linearity and new physics searches with isotope shifts
Julian C. Berengut, Cédric Delaunay, Amy Geddes +1
Atomic spectral lines for different isotopes are shifted, revealing a change in the properties of the nucleus. For spinless nuclei such isotope shifts for two distinct transitions…
Dark Matter near gravitating bodies
H. B. Tran Tan, V. V. Flambaum, J. C. Berengut
In this paper, we show that in the vicinity of certain astronomical bodies, e.g., a Neutron Star, a Black Hole, there exist significant enhancements of Dark Matter's density and cu…
Probing new light force-mediators by isotope shift spectroscopy
Julian C. Berengut, Dmitry Budker, Cedric Delaunay +8
In this Letter we explore the potential of probing new light force-carriers, with spin-independent couplings to the electron and the neutron, using precision isotope shift spectros…
