In this work, we exploit the idea of composite pulses to achieve robust population inversion
in a three-level quantum system. The scheme is based on the modulation of the coupling …

Nuclear coherent population transfer (NCPT) plays an important role in the exploration and
application of atomic nuclei. How to achieve high-fidelity NCPT remains so far challenging …

The complete population transfer from the first state to the fifth one in a five-state nuclear
system that interacts with four x-ray laser pulses has been theoretically studied using the …

Population transfer of two-state nuclei interacting with a train of composite X-ray free
electron laser (XFEL) pulses has been investigated theoretically. In this study, we calculate …

Nuclear-state population transfer in the multi-lambda systems with N= 5 that interact with
four x-ray laser pulses are investigated theoretically. By using the coincident pulses and …

The coherent superposition of states in degenerate quantum systems is investigated using
detuned laser pulses in which the Rabi frequencies are time-dependent, and the pulse area …

The technique of stimulated Raman shortcut to adiabatic passage (STIRSAP) is
implemented to chainwise and N-pod systems. In chainwise systems, for large detuning …
