Zusammenfassung:
In an ensemble of laser-driven atoms involving strongly interacting Rydberg
states, the excitation probability is usually strongly suppressed. In contrast,
here we identify a regime in which the steady-state Rydberg excited fraction is
enhanced by the interaction. This effect is associated with the build-up of
many-body coherences, induced by coherent multi-photon excitations between
collective states. The excitation enhancement should be observable under
currently-existing experimental conditions, and may serve as a direct probe for
the presence of coherent multi-photon dynamics involving collective quantum
states.
