Hybrid-order nonlinear topological phases
Yu-Peng Ma, Ming-Jian Gao, Jun-Hong An
The bulk-boundary correspondence (BBC), which relates topological invariants to boundary modes, is well understood for linear systems but remains an open question in the presence o…

Topological Phases in Non-Hermitian Nonlinear-Eigenvalue Systems
Yu-Peng Ma, Ming-Jian Gao, Jun-Hong An
The discovery of topological phases has ushered in a new era of condensed matter physics and revealed a variety of natural and artificial materials. They obey the bulk-boundary cor…
