Inversion Symmetry Breaking: Hydrogen Gradients Challenge Structural Norms in Superconductors
A new study demonstrates that creating a hydrogen concentration gradient in superconductors can induce inversion symmetry breaking, resulting in nonreciprocal charge transport. This method offers an alternative to complex artificial layering but relies on a potentially unstable nonequilibrium state.
