Dirac-vortex topological cavity
Xiaomei Gao, Lechen Yang, Hao Lin +5
Cavity design is crucial for single-mode semiconductor lasers such as the distributed feedback (DFB) and vertical-cavity surface-emitting lasers (VCSEL). By recognizing that both o…
A diagnosis scheme for topological degeneracies at high-symmetry momenta
Tiantian Zhang, Ling Lu, Shuichi Murakami +3
Theories of symmetry-based indicators and topological quantum chemistry, while powerful in diagnosing gapped topological materials, cannot be directly applied to diagnosing band de…
Crystallographic splitting theorem for band representations and fragile topological photonic crystals
A. Alexandradinata, J. Höller, Chong Wang +2
The fundamental building blocks in band theory are band representations (BRs): bands whose infinitely-numbered Wannier functions are generated (by action of a space group) from a f…
