Hidden Zeeman Field in Odd-Parity Magnets: An Ideal Platform for Topological Superconductivity
The episode discusses a paper linking odd-parity magnets to topological superconductivity via a hidden Zeeman field. Hosts explore how this intrinsic time-reversal symmetry breaking, combined with large odd-parity spin splitting, creates a robust environment for topological states. They conclude that OPMs offer material-based protection against disorder superior to external magnetic fields for scaling up quantum systems.
