Superconductor–insulator transition

The Superconductor–Insulator Transition (SIT) is a fascinating phenomenon in condensed matter physics that describes the transition between a superconducting state and an insulating state in certain materials as a function of various parameters, such as temperature, magnetic field, and disorder. In a superconducting state, materials exhibit zero electrical resistance and the expulsion of magnetic fields (Meissner effect), which typically occurs below a critical temperature.
