الوصف: | Decoherence is associated with a dissipative environment as described by the Caldeira-Leggett equation. Anglin and Zurek predicted that a resistive surface could act as such a dissipative environment for a free electron wave passing close to it. We scrutinize Zurek's and other promising decoherence theoretical models by observing electrons passing by an optically excited GaAs surface and through a gold channel. The high resistivity of the GaAs surface and close proximity to the gold surface leads to strong decoherence within these decoherence models. In contradistinction, the observed contrast is high in our electron diffraction patterns. This implies lower decoherence rates than suggested by these models, making electron-matter-wave-guides and other technologies, where quantum coherence of electrons close to materials is important, a possibility Comment: 11 pages, 7 figures |
