Momento electromagnético, efectos cuánticos y la masa del fotón

G. Spavieri, J. Erazo, A. Sánchez, M. Rodriguez


We review the role of the momentum of the electromagnetic (EM)
fields $\mathbf{P}_{e}$ in several areas of modern physics,
revising the most recent achievements and its relationship with
$\mathbf{P}_{e}$. The moment $\mathbf{P}_{e}$ represents the EM
interaction in equations for matter and light waves propagation.
As an application of wave propagation properties, a first order
optical experiment which tests the speed of light in moving
rarefied gases is presented. Moreover, $\mathbf{P}_{e}$ is the
link to the unitary vision of the quantum effects of the
Aharonov-Bohm (AB) type and, for several of these effects, the
explicit expression of $\mathbf{P}_{e}$ is evaluated. Finally,
these effects provide a quantum approach to evaluate the limit of
the photon mass~$m_{ph}$. A new effect of the AB type, together
with the scalar AB effect, provides the basis for table-top
experiments which yield the limit
$m_{ph}\simeq9.4\times10^{-52}$g, a value that improves the
results achieved with recent classical and quantum approaches.
