STIRAP (stimulated Raman adiabatic passage) is a powerful laser-based method, usually
involving two photons, for efficient and selective transfer of populations between quantum …

Population of the 8 eV Th 229 m isomer via the second nuclear excited state at 29.19 keV by
means of coherent x-ray pulses is investigated theoretically. We focus on two nuclear …

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 …

Ammonia is special. It is nonplanar, yet in v= 1 of the umbrella mode (ν2) its inversion motion
is faster than J= 0↔ 1 rotation. Does the simplicity of the Chemist's concept of an electric …

Nuclear-state population transfer in three-level Λ-like nuclei that interact with two X-ray laser
pulses using composite stimulated Raman adiabatic passage (CSTIRAP) technique is …

In this paper, an exact analytical solution is presented for achieving coherent population
transfer and creating arbitrary coherent superposition states in a five-state chainwise system …

The generation of arbitrary preselected coherent superposition of states in multi-state
systems using adiabatic pulses split by a phase jump has been investigated. We consider a …
