Precision Test of Mass-Ratio Variations with Lattice-Confined Ultracold Molecules
Precision Test of Mass-Ratio Variations with Lattice-Confined Ultracold Molecules
We propose a precision measurement of time variations of the proton-electron mass ratio using ultracold molecules in an optical lattice. Vibrational energy intervals are sensitive to changes of the mass ratio. In contrast to measurements that use hyperfine-interval-based atomic clocks, the scheme discussed here is model independent and does not …
