Free-standing, axially-symmetric diffraction gratings for neutral matter-waves: experiments and fabrication
(The University of Bergen, 2011-10-04)
Since de Broglie’s famous postulation of the wave-nature of material particles and its subsequent experimental verification, it is known that atoms and molecules behave like waves on a small scale. The investigation of ...
Particle–wave discrimination in Poisson spot experiments
(IOP Publishing Ltd, 2011)
Matter–wave interferometry has been used extensively over the last few years to demonstrate the quantum-mechanical wave nature of increasingly larger and more massive particles. We have recently suggested the use of ...
Neutral atom and molecule focusing using a Fresnel zone plate
(American Institute of Physics, 2008)
Focusing of neutral atoms and molecules has several potential applications. The very first microscopy images using helium as an imaging probe were published earlier this year. Another possible application is to study the ...
Poisson’s spot with molecules
(The American Physical Society, 2009)
In the Poisson-spot experiment, waves emanating from a source are blocked by a circular obstacle. Due to their positive on-axis interference an image of the source the Poisson spot is observed within the geometrical shadow ...
