Cooperative lamb shift
WebJun 15, 2010 · Cooperative Lamb shift in an ellipsoid Full Record Related Research Abstract It has been long known that the global cooperative Lamb shift (CLS) in a large superradiantly emitting sphere has equal magnitude but opposite sign to that of a slab. This result was obtained from QED in 1973 for samples of uniform density. WebApr 13, 2024 · We show that the Lamb shift can significantly affect the nature of the interatomic dipole-dipole interaction in structured reservoirs. The effect is explained by the difference in the Lamb shift for atoms located at different positions due to the inhomogeneity of the spatial structure of the modes of the electromagnetic field. Based …

WebThe collective Lamb shift is a cooperative optical effect that is intimately connected with the phenomenon of superradiance, i.e., the cooperative spontaneous emission of radiation … WebJun 4, 2010 · The collective coupling of the atoms via the radiation field leads to a substantial radiative shift of the transition energy, the collective Lamb shift. We simultaneously measured the temporal evolution of the superradiant decay and the collective Lamb shift of resonant 57Fe nuclei excited with 14.4-kilo-electron volt …
WebObserving the collective Lamb shift is challenging, since it can be obscured by radiative decay and direct atom-atom interactions. Here, we place two superconducting qubits in a transmission line terminated by a mirror, which suppresses decay. WebWe 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. …
