  1. Superconductivity arises when electrons form Cooper pairs mediated by lattice vibrations, a state that collapses once thermal energy disrupts phase coherence.

  2. The critical temperature (Tc) marks the threshold where kT equals the binding energy of pairs—thus, higher Tc requires stronger electron-phonon coupling or unconventional pairing mechanisms.
