Photons Generated Just By Moving A Mirror?

Yes.

The Dynamical Casimir Effect is a quantum phenomenon predicted by quantum field theory, where an oscillating uncharged mirror in a vacuum generates electromagnetic radiation, or photons.

Unlike classical physics, where electromagnetic radiation arises from moving charged particles like electrons, the DCE occurs due to the interaction between the moving mirror and quantum vacuum fluctuations.

This interaction causes virtual photons (those that exist momentarily due to quantum uncertainty) to be upconverted into real photons, which then propagate away from the mirror. https://x.com/BrianRoemmele/status/1900391798230704503
