What are the two defining experimental signatures of superconductivity?1 / 7

(1) Zero DC electrical resistance below a critical temperature T_c — persistent currents have been observed to flow essentially undiminished for years. (2) The Meissner effect — a superconductor actively expels magnetic field from its interior, not merely a consequence of zero resistance (a perfect conductor alone would only trap flux, not expel it).

How does quantum optics treat a single mode of the electromagnetic field, in terms of familiar quantum mechanics?1 / 7

Each mode of the quantised EM field is mathematically equivalent to a quantum harmonic oscillator, with photon number states |n⟩ playing the role of oscillator energy eigenstates, and raising/lowering (creation/annihilation) operators â† and â that add or remove one photon of energy ℏω.
