Spontaneous Chern-Euler Duality Transitions
Kang Yang, Zhi Li, Peng Xue +2
Topological phase transitions are typically characterized by abrupt changes in a quantized invariant. Here we report a contrasting paradigm in spontaneous parity-time symmetry-brea…

Exceptional topology on nonorientable manifolds
J. Lukas K. König, Kang Yang, André Grossi Fonseca +3
We classify gapped phases and characteristic nodal points of non-Hermitian band structures on two-dimensional nonorientable parameter spaces. Such spaces arise in a wide range of p…
