Detuned-KCQ ground state and its energy with . (A) The fractional deviation of the ground state energy estimated by the unperturbed Hamiltonian and perturbation theory. (B) The difference between the coherent state and the ground state of the detuned-KCQ Hamiltonian calculated by numerical diagonalization (ND) and perturbation theory (PT).
