How does QED at a finite temperature differ from QED at zero temperature?

Do electrons really perform instantaneous quantum leaps?

Why don't electron-positron collisions release infinite energy?

Why doesn't there exist a wave function for a photon whereas it exists for an electron?

Why does the fine-structure constant $α$ have the value it does?

How can I do quantum chemistry with QED?

What are quantum fluctuations, really?

What is the experimental evidence for a quantized EM field?

Is it possible to have renormalisable C-, P-, or T-violating terms in QED?
