Correlation between superconductivity and disorder remains an intriguing and challenging puzzle in condensed matter physics. According to the Bardeen– Cooper–Schrieffer (BCS) theory, the superconducting phenomenon emerges due to the binding of mobile electrons into Cooper pairs that forms a macroscopic quantum coherent state. For a weakly disordered system, the wellknown Anderson theorem states that superconductivity is insensitive to disorder factors, such as elastic scattering centers, not affecting the time-reversal symmetry. Nevertheless, this statement is valid only for initially isotropic, homogeneous, and weak-coupling materials.
