WebFeb 23, 2024 · 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 2k, i.e. twice that of the optical field. WebMay 9, 2024 · Nevertheless, the phrase “cooperative Lamb shift” is used repeatedly to refer to other quantities. In particular, [3,4,7] citing [1], give for the “CLS” in a slab of thickness L the formula D = DLL 3 4 DLL(1 sin(2kL) 2kL), (6) where DLL = 4 3 np 2/¯h is the Lorentz shift. In terms of S = np2/¯h, this can be written D = 4 3

WebNov 5, 2014 · Here, we report a direct spectroscopic observation of the cooperative Lamb shift of an optical electric-dipole transition in an array of Sr(+) ions suspended in a Paul trap at inter-ion separations much larger than the resonance wavelength. By controlling the precise positions of the ions, we studied the far-field resonant coupling in chains of ...
