# Integrability of the Rabi model.

@article{Braak2011IntegrabilityOT, title={Integrability of the Rabi model.}, author={Daniel Braak}, journal={Physical review letters}, year={2011}, volume={107 10}, pages={ 100401 } }

The Rabi model is a paradigm for interacting quantum systems. It couples a bosonic mode to the smallest possible quantum model, a two-level system. I present the analytical solution which allows us to consider the question of integrability for quantum systems that do not possess a classical limit. A criterion for quantum integrability is proposed which shows that the Rabi model is integrable due to the presence of a discrete symmetry. Moreover, I introduce a generalization with no symmetries…
