Which outcome occurs when trapped Josephson junction electrons exceed critical density?

A)Macroscopic Quantum Self-Trapping appears
B)Resistance rises exponentially
C)Increased cooper pair formation efficiency
D)Junction returns to insulating state

💡 Explanation

Macroscopic Quantum Self-Trapping appears because enhanced electron-electron interaction introduces nonlinear terms. Therefore, a self-trapped coherent state emerges, observable at the device scale, rather than Cooper pair changes normally found at lower electron densities.
