Abstract

Using the time-dependent multilevel approach (TDMA) and B-splines function,we have calculated the five quantum state population transfer of rydberg lithium atoms.We also analyse the influence of the four major parameters of the requency-chirped laser pulses field on transition.The result shows that the population can be completely transferred to the target state by changing the parameters of the laser pulse and achieve manual controls to a certain degree.

Using the time-dependent multilevel approach (TDML),we have calculated the coherent population transfer among the quantum states of lithium atom with different frequency-chirped laser pulses. The result shows that the population is very sensitive to the parameters of laser pulse,the population can be completely transferred to the target state and be trapped there by changing the parameters of the laser pulse.

Coherent excitation and control of Rydberg lithium atoms in a chirped microwave field

The time-dependent multilevel approach (TDMA) and the B-spline expansion technique are used to study the properties of Rydberg lithium atom. The energy level structures of high excited states n = 7075, l = 05 and population transfer of lithium atom in a microwave field are studied by numerical calculation. The results show that the coherent control of the population transfer in microwave field from the initial to the target states can be accomplished by optimizing the microwave field parameters. and that each state plays a crucial role in the transition process.

Laser pulse design for coherent control of Rydberg lithium atoms

Xianzhou Zhang, Wu Su-Ling, Lijuan Jiang +2 more

Using the time-dependent multilevel approach (TDML), this paper studies the dynamics of coherent control of Rydberg lithium atoms and demonstrates that Rydberg lithium atoms can be transferred to states of higher principal quantum number by exposing them to specially designed frequency-chirped laser pulses. The population transfer from n = 70 to n = 75 states of lithium atoms with efficiency of more than 90% is achieved by means of the sequential adiabatic rapid passages. The results agree well with the experimental ones and show that the coherent control of the population transfer from the lower n to the higher n states can be accomplished by the optimization of the chirping parameters and the intensity of laser field.

Lijuan Jiang, Xianzhou Zhang, Ma Huan-Qiang +2 more

Using the time-dependent multilevel approach and the B-spline technique, populations of Rydberg lithium atoms in chirped microwave pulses are demonstrated. Firstly the populations of two energy levels are controlled by the microwave pulse parameters. Secondly the atoms experience the consequence 70s-71p-72s-73p-74s in a microwave field using optimized microwave field parameters. It is shown that the coherent control of the population transfer in the microwave field from the initial to the target states can be accomplished by optimizing the microwave field parameters.
