Fecha de publicación: | 2010 | Editor: | Royal Swedish Academy of Sciences | Citación: | Physica Scripta T140: 014017 (2010) | Resumen: | Here, the influence of resonance photon-atom scattering on the atom interference pattern at the exit of a three-grating Mach-Zehnder interferometer is studied. It is assumed that the scattering process does not destroy the atomic wave function describing the state of the atom before the scattering process takes place, but only induces a certain shift and change of its phase. We find that the visibility of the interference strongly depends on the statistical distribution of transferred momenta to the atom during the photon-atom scattering event. This also explains the experimentally observed (Chapman et al 1995 Phys. Rev. Lett. 75 2783) dependence of the visibility on the ratio d(p)/lambda(i) = y'(12)(2 pi/kd lambda(i)), where y'(12) is the distance between the place where the scattering event occurs and the first grating, k is the wave number of the atomic centre-of-mass motion, d is the grating constant and lambda(i) is the photon wavelength. Furthermore, it is remarkable that photon-atom scattering events happen experimentally within the Fresnel region, i.e. the near-field region, associated with the first grating, which should be taken into account when drawing conclusions about the relevance of 'which-way' information for the interference visibility. | URI: | http://hdl.handle.net/10261/92529 | DOI: | 10.1088/0031-8949/2010/T140/014017 | Identificadores: | doi: 10.1088/0031-8949/2010/T140/014017 issn: 0031-8949 |
