Deskripsi
We discuss the elementary errors in Zhang’s (2021 New J. Phys. 23 093014) claimed exact solution of the quantum Rabi model. The erroneous solution is seen to be nothing more than the combined solution of the simpler Jaynes–Cummings and anti-Jaynes–Cummings models obtained by neglecting terms in the model Hamiltonian.
