The difference between the electron's cyclotron frequency and its spin precession frequency in a magnetic field is proportional to g−2. An extremely high precision measurement of the quantized energies of the cyclotron orbits, or Landau levels , of the electron, compared to the quantized energies of the electron's two possible spin ...
They used a radio frequency separator (RFS) to measure time-of-flight differences and thus velocity differences between those electrons and 15-GeV gamma rays on a path length of 1015 m. They found no difference, increasing the upper limit to Δ v / c = 2 × 10 − 7 {\displaystyle \Delta v/c=2\times 10^{-7}} .
According to the latter mass value and the formula for relativistic energy, relative speed differences between light and neutrinos are smaller at high energies, and should arise as indicated in the figure on the right. Time-of-flight measurements conducted so far investigated neutrinos of energy above 10 MeV.
Relation between the speed and the Lorentz factor γ (and hence the time dilation of moving clocks). Time dilation as predicted by special relativity is often verified by means of particle lifetime experiments. According to special relativity, the rate of a clock C traveling between two synchronized laboratory clocks A and B, as seen by a ...
The recorded temperature differences were used to correct the data before analysis. [5] Among the other steps used to compensate for possible systematic errors, Pound and Rebka varied the speaker frequency between 10 Hz and 50 Hz and tested different transducers (ferroelectric transducers versus moving coil magnetic speaker coils).

Quantum state tomography is a process by which, given a set of data representing the results of quantum measurements, a quantum state consistent with those measurement results is computed. [50] It is named by analogy with tomography, the reconstruction of three-dimensional images from slices taken through them, as in a CT scan.
The relationship between frequency (proportional to energy) and wavenumber or velocity (proportional to momentum) is called a dispersion relation. Light waves in a vacuum have linear dispersion relation between frequency: ω = c k {\displaystyle \omega =ck} .
summed over all allowed initial and final states leading to the energy and momentum being observed. [2] Here, E is measured with respect to the Fermi level E F, and E k with respect to vacuum so = + where , the work function, is the energy difference between the two referent levels. The work function is material, surface orientation, and ...
