Then-level,n− 1-mode Jaynes–Cummings model: spectrum and eigenvectors
T. Skrypnyk · Journal of Physics A Mathematical and Theoretical · 2013
We explicitly find eigenvectors and eigenvalues of the general n -level, n − 1-mode Jaynes–Cummings model in Λ-configuration possessing arbitrary detuning parameters Δ i , and arbitrary interaction strengths g i , . In the case of equal interaction strengths g i = g j , , we compare the obtained answers with those obtained by the algebraic Bethe ansatz method (Skrypnyk 2008 J. Phys. A: Math. Theor. 41 475202; 2009 J. Math. Phys. 50 103523).
