Oscillating nuclear charge radii as sensors for ultralight dark matter
Abhishek Banerjee, Dmitry Budker, Melina Filzinger +5
We show that coupling of ultralight dark matter (UDM) to quarks and gluons would lead to an oscillation of the nuclear charge radius for both the quantum chromodynamics (QCD) axion…

Probing an ultralight QCD axion with electromagnetic quadratic interaction
Hyungjin Kim, Alessandro Lenoci, Gilad Perez +1
The axion-gluon coupling is the defining feature of the QCD axion. This feature induces additional and qualitatively different interactions of the axion with standard model particl…
