Homotopy, Symmetry, and Non-Hermitian Band Topology
Kang Yang, Zhi Li, J. Lukas K. König +3
Non-Hermitian matrices are ubiquitous in the description of nature ranging from classical dissipative systems, including optical, electrical, and mechanical metamaterials, to scatt…
Emergent Chern-Simons Interactions in 3+1 Dimensions
Marcus Stålhammar, Darya Rudneva, Thors Hans Hansson +1
Parity violating superconductors can support a low-dimension local interaction that becomes, upon condensation, a purely spatial Chern-Simons term. Solutions to the resulting gener…
Fractal Nodal Band Structures
Marcus Stålhammar, Cristiane Morais Smith
Non-Hermitian systems exhibit interesting band structures, where novel topological phenomena arise from the existence of exceptional points at which eigenvalues and eigenvectors co…
