We develop exact and physically transparent approximate methods for Rabi-type models, investigate exceptional solutions and conical intersections, and study how hidden symmetries emerge when conventional parity symmetry is broken.</p> <p>Our work spans Rabi and Dicke models, hidden symmetry, tunneling dynamics, and geometric phases. Generalized adiabatic approximations and variational approaches connect analytical structure with experimentally relevant regimes of ultrastrong coupling.</p> <p>Representative publications include <a href="https://doi.org/10.1103/PhysRevA.103.023719" target="_blank" rel="noopener">Hidden symmetry and tunneling dynamics (2021)</a> and <a href="https://doi.org/10.1103/PhysRevA.104.033712" target="_blank" rel="noopener">Generalized adiabatic approximation (2021)</a>.</p>
