-symmetric quantum mechanics
It is generally assumed that a Hamiltonian for a physically acceptable quantum system (one
that has a positive-definite spectrum and obeys the requirement of unitarity) must be …

The dispersion and propagation of topological Langmuir-cyclotron waves in cold magnetized plasmas
The topological Langmuir-cyclotron wave (TLCW) is a recently identified topological surface
excitation in magnetized plasmas. We show that TLCW originates from the topological …

Topological modes and spectral flows in inhomogeneous PT-symmetric continuous media
In classical Hermitian continuous media, the spectral-flow index of topological modes is
linked to the bulk topology via index theorem. However, the interface between two bulks is …

Vorticity wave interaction, Krein collision, and exceptional points in shear flow instabilities
C Meng, Z Guo - Physical Review E, 2023 - APS
We relate the model of vorticity wave interaction to Krein collision, PT-symmetry breaking,
and the formation of exceptional points in shear flow instabilities. We show that the …
