One recent experiment backs up Minkowski's answer — but still may not prove Abraham wrong. One might expect that the momentum of a photon, under almost any conditions, would no longer be a ...

In this study, a qudit was implemented by the orbital angular momentum state of a single-photon, and dimensional expansion was possible by adjusting the phase of a photon through holographic images.
