← ScienceWhich mechanism causes zero resistance approaching absolute zero?
A)Cooper pair quantum phase coherence✓
B)Increased electron-phonon scattering rate
C)Suppressed magnetic domain formation energy
D)Enhanced lattice vibrational thermal conductivity
💡 Explanation
Materials become superconducting because Cooper pair quantum phase coherence enables electrons to move without scattering below the critical temperature; therefore, resistance drops towards zero, rather than remaining finite due to electron energy loss.
