Structural and dynamical aspects of avoided-crossing resonances in a $3$-level $\Lambda$ system

TL;DR

This paper investigates the differences between structural and dynamical definitions of avoided-crossing resonances in a 3-level Lambda system, proposing an experiment with alkali atoms to observe these distinctions.

Contribution

It clarifies the distinction between two definitions of avoided-crossing resonances and proposes an experimental setup to observe their differences in a 3-level system.

Findings

Distinct resonance conditions identified for structural and dynamical definitions.

Proposed microwave experiment to observe the difference in alkali atoms.

Enhanced understanding of resonance behavior in quantum systems.

Abstract

In a recent publication [Phys. Rev. A 79, 065602 (2009)] it was shown that an avoided-crossing resonance can be defined in different ways, according to level-structural or dynamical aspects, which do not coincide in general. Here a simple $3$-level system in a $\Lambda$ configuration is discussed, where the difference between both definitions of the resonance may be observed. We also discuss the details of a proposed experiment to observe this difference, using microwave fields coupling hyperfine magnetic sublevels in alkali atoms.
