24 May 2016 | | Abstract: | We propose a method to improve the stimulated Raman adiabatic passage via
dissipative quantum dynamicas, taking into account the dephasing effects. Fast
and robust population transfer can be obtained by the designed pulses and
detuning, even though the initial state of the system is imperfect. With a
concrete three-level system as a example, the influences of the imperfect
initial state, variations in the control parameters, and various dissipation
effects are discussed in detail. The numerical simulation shows that our scheme
is insensitive to moderate fluctuations of experimental parameters and the
relatively large dissipation effects of the excited state. Furthermore, the
dominant dissipative factors, the dephasing effects of the ground states and
the imperfect initial state are no longer undesirable, in fact, they are the
important resources to our scheme. Therefore, our scheme could provide more
choices for the realization of the complete population transfer in the strong
dissipative fields where the standard STIRAP or shortcut schemes are invalid. | | Source: | arXiv, 1605.7274 | | Services: | Forum | Review | PDF | Favorites | |
