Non-Hermitian physics

Symmetry gives rise to an elegant catastrophe

Nature Physics volume 19, pages 1073–1074 (2023)Cite this article

Subjects

Imposing PT-symmetry and pseudo-Hermitian symmetry on an electric circuit with non-reciprocal couplings results in a complex morphology of degenerate eigenvalues that might yield new possibilities in sensing and dynamical engineering.
