Exploring Spectral Singularities in Dirac Semimetals: The Role of Non-Hermitian Physics and Dichroism
Dichroic Dirac semimetals generate 12 unique topological laser types via spectral singularities, surface currents from topological terms, and the distinct role of the θ term, with stable topological properties.
