Abstract: The study of unconventional phases and elucidation of correspondences between topological invariants and their intriguing properties are pivotal in topological physics. Here, we investigate a complex exceptional ring (CER), composed of a third-order exceptional ring… read more here.

Abstract: We investigate the energy band structure and exceptional ring in a two-dimensional superconducting circuit lattice. In the case of a Hermitian Hamiltonian, by modulating the on-site potential, we find that the single Dirac point splits… read more here.
