摘要

An integrable non-Hermitian generalized Rabi model is constructed.A twist matrix is introduced to the construc-tion of Hamiltonian and generates the non-Hermitian properties.The Yang-Baxter integrability of the system is proven.The exact energy spectrum and eigenstates are obtained using the Bethe ansatz.The method given in this study provides a general way to construct integrable spin-boson models.
