Bubbles and other confined spaces...

Cavity QED induced photoelectric effect

• Surface tension separates a central core of atoms from bubble wall
• Each atom in the core emits 3/2 KT of IR radiation
• VUV bubble cavity momentarily suppresses IR radiation
• IR radiation promptly released as coherent multi-IR photons
• Multi-IR photons combine to VUV levels
• Electrons produced by photoelectric effect
