Odd ways to unconventional superconductivity

Superconductivity is a fascinating state of matter that transforms metals at very low temperature into perfect conductors and perfect diamagnets. Superconductivity with a wave function of odd parity is interesting for its robustness to magnetic field and possible topological properties. But this state is extremely rare. I will show how local asymmetry of the lattice in the compound CeRh₂As₂ leads to a phase transition induced by magnetic field that is currently understood as a transition from an even-parity to an odd-parity superconducting state.
