“…To illustrate this, we also plot the theoretical prediction with the line shift removed. From fitting the data, the collisional broadening is found to be 3 for thicknesses greater than =4 in agreement with previous work (see [23] and references therein). For thicknesses shorter than =4, we observe additional broadening that requires further investigation.…”

We present an experimental measurement of the cooperative Lamb shift and the Lorentz shift using a nanothickness atomic vapor layer with tunable thickness and atomic density. The cooperative Lamb shift arises due to the exchange of virtual photons between identical atoms. The interference between the forward and backward propagating virtual fields is confirmed by the thickness dependence of the shift, which has a spatial frequency equal to twice that of the optical field. The demonstration of cooperative interactions in an easily scalable system opens the door to a new domain for nonlinear optics.

“…Experiments on the low-temperature limit of cavity QED have shown that spontaneous emission rates are altered [4][5][6] and that atomic levels are shifted [7][8][9]. By comparison, the effects of a cavity at nonzero temperature have hardly been studied.…”

“…The decay rates become dependent on the intensity of the driving field, because the dynamics of the Bloch vector S(t) appearing in (12) is governed by the Rabi oscillations. If the Rabi frequency exceeds the cavity linewidth K, averaging of the correlation function (S+ (t -τ)S (t)) over a time K -1 rednces expression (12), and hence the decay rate Γ | , to almost rćro.…”

“…Since there is no mode available for the atom to interact with, it cannot emit the stored energy and the lifetime in the excited state is increased. Both enhancement and inhibition of spontaneous emission have been observed in the optical domain [9] as well as with microwave transitions between highly excited Rydberg levels [10][11][12].…”

We investigated the dynamically modified interaction between Rydberg atoms and a single mode of a microwave cavity driven by a strong external field. With a monochromatic injected field we observed dynamic suppression of spontaneous emission, when the intracavity Rabi frequency exceeds the cavity linewidth. We discuss a theoretical model using non-Markovian decay rates, which is in excellent agreement with experiment. When a bichromatic driving field is used, enhanced decay reappears in narrow resonance zones as the detunings and injected intensities are varied. These results are interpreted in terms of cavity-modified transitions between the Floquet states of a two-level atom. Striking aspects of these transitions are their small linewidth and an asymmetry between emission and absorption.
