Microwave photons can nullify the conductivity of electrons confined to the surface of liquid helium
Trapping electrons in a flat plane prevents them from moving freely in the third dimension and opens the door to a whole range of unusual physics. These effects are harnessed, for example, in modern ultrafast ...
