Non-Hermitian Physics

Exploring how gain, loss, and environmental coupling reshape quantum spectra, dynamics, and steady states, with a focus on exceptional points, dissipative phase transitions, and anomalous relaxation.

Our 2026 Physical Review A paper shows how topological edge states and exceptional points can jointly improve the charging dynamics of an SSH quantum battery.

A PT-symmetric SSH quantum battery uses topology and non-Hermiticity to enhance charging dynamics through edge-state exceptional points.

The interplay of rotating and counterrotating interactions with two-photon relaxation is a central problem in quantum optics and …

We study quantum light-matter interaction, open quantum systems, non-Hermitian physics, and quantum information, combining analytical methods with numerical calculations.
