Wave-particle duality of C60 molecules

Article Abstract:

It has been possible to observe de Broglie wave interference of C60 molecules by diffraction at a material absorption grating. All the observations supported the view that each C60 molecule interferes only with itself. C60 is nearly a classical body, as a result of its many excited internal degrees of freedom and their potential couplings to the environment. Further research should consider the interference of objects the size of which is equal to or even larger than the diffracting structure.

A quantum scattering interferometer

Article Abstract:

The quantum scattering phase shifts of individual atoms are detected by using a novel atom interferometer. The scattering experiment will enable direct measurements of ultracold atom-atom interactions and it can be used to place stringent limits on the time variations of fundamental constants.

Decoherence of matter waves by thermal emission of radiation

Article Abstract:

Decoherence refers to the processes that limit the appearance of quantum effects and turn them into classical phenomena. A report on wave interferometer experiments in which carbon molecules lose their quantum behavior by thermal emission of radiation, is presented.
