Dark matter physics
WebPhysicists have established that dark matter must have mass and exert gravity, but it must also be relatively slow-moving, and its interactions (other than gravity) with known particles must be weak or absent. WebApr 11, 2024 · Atomic spectroscopy is used to search for the space-time variation of fundamental constants which may be due to an interaction with scalar and pseudo-scalar (axion) dark matter. In this letter, we study the effects which are produced by the variation of the nuclear radius and electric quadrupole moment. The sensitivity of the electric …
