We are all taught that there are only two polarizations of light because Maxwell’s equations only support two polarizations. This is mathematically true for the electromagnetic fields, but we have learned since the days of Maxwell that the “real” electromagnetic field is not the electromagnetic field tensor Fμv (composed of Electric and Magnetic field terms) but rather the electromagnetic vector potential Aμ. When considered carefully, this requires a third polarization of light with very unusual properties. This third polarization of light does not generate electric or magnetic fields but should be detectable by its impact on supercurrents or quantum interference. It is also unavoidable since it automatically appears under Lorentz transformations to different moving frames.
Much of our tradition in E&M theory is that the electric and magnetic fields are the reality, and the vector potential is a computational convenience. However, for over half a century, the evidence has accumulated that the vector potential is the fundamental field, and the SQUID experiment without any E or B fields touching the circuitry is the extreme verification of that hypothesis. Once we reach that conclusion and show that a third polarization cannot be avoided in a Lorentz invariant universe, then we need to consider the possibility that there is a physical third polarization of light that interacts very differently from the other two.
Assuming this result of a third polarization stands up to review, it would seem to be an opportunity for experimentalists to try to detect and characterize it. The logical place to begin is an AC superconducting experiment that can differentiate between conventional E&M waves and vector potential waves. Since the field amplitude matches k, it will generate a supercurrent oscillating in the direction of light propagation, while conventional E&M light waves create currents perpendicular to the direction of propagation―a simple discriminator.Also, suppose we take a source of light and pass it through X and Y wire grid polarizers. The third polarization, without any E and B fields to generate wire grid currents, would pass through the polarizers and still interact. Alternatively, perhaps this mode will penetrate through room temperature opaque materials without being absorbed well since it has no E and B fields to interact, allowing another detection discriminator.Experiments always have the last word.
