Equation 9 · Part 1 · The Corner of the Equivalence Principle No Experiment Has Touched
Symbol hateta_diag
What this part means
diagonal in the internal energy basis: it can make a clock in one internal state fall differently from the same species in another, which is what a clock-redshift test or a test comparing atoms prepared in different hyperfine states actually probes.
Its job in the formula
hatetiag is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.
Where the article explains it

The passage around this formula
is an ordinary number, the same for every state — MICROSCOPE’s slot. is diagonal in the internal energy basis: it can make a clock in one internal state fall differently from the same species in another, which is what a clock-redshift test or a test comparing atoms prepared in different hyperfine states actually probes. is off-diagonal…
