Manipulation of Population Transfer to Atomic Superposition States: An Extension of Stimulated Raman Adiabatic Passage to a Four-level Ladder System

Yueping Niu, Shangqing Gong

Abstract

We extend the existing theory of stimulated Raman adiabatic passage to a four-level ladder system for realizing superposition of two high-lying Rydberg states by applying a control field to couple them. We find, due to the effect of the control field, that population is completely transferred from the initial level to a superposition of the two high-lying states. Suitable manipulation of the control field and detunings makes it possible to create any coherent superposition states we desired.
