$mc^2/\hbar$

Why this formula appears here

Here is the strongest objection this construction has to survive, and it is not hypothetical — it was argued in print for over a decade. In 2010, Müller, Peters, and Chu proposed that an ordinary light-pulse atom interferometer’s gravimeter phase already constitutes a measurement of the gravitational redshift at the atom’s Compton frequency m $c^2$ / $\hbar$ , reading the standard interferometer as an implicit realization of exactly the proper-time phase this paper formalizes [ 6 ] . Wolf, Blanchet, Bordé, Reynaud, Salomon, and Cohen-Tannoudji objected immediately: the standard three-pulse Mach–Zehnder gravimeter phase, computed by the ordinary classical-action method, is $\phi$ $\approx$ k_{ $\rm$ …
