Measurement of the variation of electron-to-proton mass ratio using ultracold molecules produced from laser-cooled atoms
Ultracold molecules are suitable platforms for precision measurements due to their internal degrees of freedom. Here the authors derive a limit on the variation of the electron-to-proton mass ratio by using the spectroscopy of ultracold KRb molecules.
