Quantum Mechanics and Non-Hermitian Physics

This cluster of papers explores the concept of Parity-Time (PT) symmetry in optics and quantum mechanics, focusing on non-Hermitian physics, exceptional points, topological phases, and nonlinear systems. It investigates phenomena such as PT-symmetric optical lattices, exceptional points in photonics, and the implications of PT symmetry for quantum mechanics and optical devices.
