Research Directions and Our Group

Our group is based in the School of Physics at Central South University. We study how quantum systems exchange energy and information with light fields and their surrounding environments. Our work combines analytical methods, numerical calculations, and physically transparent models.

Our current research has four closely connected themes:

• Quantum Rabi models and light-matter interaction. We develop exact and approximate methods for strongly coupled qubit-oscillator systems and investigate their spectra, eigenstates, and dynamics.
• Open quantum systems. We study how relaxation, dissipation, and environmental noise reshape quantum dynamics and steady states.
• Non-Hermitian physics. We explore parity-time symmetry, exceptional points, and the interplay between gain, loss, and quantum coherence.
• Quantum information and energy science. We are interested in entanglement generation, state preparation, and quantum batteries.

Graduate and undergraduate students participate in different parts of these projects, from analytical derivations and numerical simulations to literature review and scientific visualization. We welcome discussions and collaborations in quantum optics and related areas.
