Nonlinear oscillator behavior in the Jaynes-Cummings model
Y.-T. Chough, H. J. Carmichael · Physical Review A · 1996
The driven Jaynes-Cummings model shows collapses and revivals of the mean photon number on a time scale much longer than the revival time for the two-state inversion. The behavior is essentially that of a nonlinear quantum oscillator with Hamiltonian H=\ensuremath{\surd}(A${\mathrm{^}}^{\mathrm{\ifmmode^\circ\else\textdegree\fi{}}}$+\ensuremath{\alpha})(A^+\ensuremath{\alpha}). \textcopyright{} 1996 The American Physical Society.
