Hamiltonian Reduction of Quantum Systems Controlled by Pulses
《Chinese Journal of Chemical Physics》2011年第4期378-382,I0003,共6页徐强 王耀雄 双丰 H.Rabitzc 
ACKNOWLEDGMENTS This work was supported by the National Natural Science Foundation of China （No.61074052 and No.61072032）. Herschel Rabitz acknowledges the support from Army Research Office （ARO）.
We explores Hamiltonian reduction in pulse-controlled finite-dimensional quantum systems with near-degenerate eigenstates. A quantum system with a non-degenerate ground state and several near-degenerate excited states...
