Symmetry-protected exceptional and nodal points in non-Hermitian systems

S Sayyad, M Stålhammar, L Rødland, FK Kunst - SciPost Physics, 2023 - scipost.org
One of the unique features of non-Hermitian (NH) systems is the appearance of NH
degeneracies known as exceptional points (EPs). The extensively studied defective EPs …
