Quantum control of population transfer and vibrational states via chirped pulses in four level density matrix equations

We investigate the effect of chirped excitation and the excitation detuning on the coherent control of population transfer and vibrational states in a four-­--level system. Density matrix equations are studied for optimally enhanced processes by considering specific parameters typical of oxazine sys...
