AB - 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 require separation of time variations of different
physical constants. The possibility of applying the zero-differential –Stark-shift optical lattice technique is
explored to measure vibrational transitions at high accuracy.
