| A proof of odd-parity superconductivity Posted: 12 Jul 2022 11:12 AM PDT Superconductivity is a fascinating state of matter in which an electrical current can flow without any resistance. Usually, it can exist in two forms. One is destroyed easily with a magnetic field and has 'even parity', i.e. it has a point symmetric wave function with respect to an inversion point, and one which is stable in magnetic fields applied in certain directions and has 'odd parity', i.e. it has an antisymmetric wave function. |
