An interferometer for atoms.
We have demonstrated an interferometer for atoms. A three-grating geometry is used, in which the interfering beams are distinctly separated in both position and momentum. We used a highly collimated beam of sodium atoms with a de Broglie wavelength of 16 pm and high-quality 0.4-pm-period freestanding gratings which we fabricated using a novel method. The interference signal is 70 counts/s, whic...
متن کاملAn electron Talbot interferometer
The Talbot effect [1], in which a wave imprinted with transverse periodicity reconstructs itself at regular intervals, is a diffraction phenomenon that occurs in many physical systems. Here we present the first observation of the Talbot effect for electron de Broglie waves behind a nanofabricated transmission grating. This was thought to be difficult because of Coulomb interactions between elec...
متن کامل1 An Interferometer for Atoms
We have demonstrated a novel diffraction grating for atoms. Acollimated beam of sodium atoms with a de Broglie wavelength of 17picometers was diffracted by transmission through an array of slitswith a spatial period of 0.2 μm formed in a gold membrane. This isthe first reported diffraction of atoms by a fabricated periodicstructure. Our transmission diffraction grating for a...
متن کاملAn Electromechanical Which–Path Interferometer
We investigate the possibility of an electromechanical which–path interferometer, in which electrons travelling through an Aharonov–Bohm ring incorporating a quantum dot in one of the arms are dephased by an interaction with the fundamental flexural mode of a radio frequency cantilever. The cantilever is positioned so that its tip lies just above the dot and a bias is applied so that an electri...
متن کاملError Analysis, Design and Modeling of an Improved Heterodyne Nano-Displacement Interferometer
A new heterodyne nano-displacement with error reduction is presented. The main errors affecting the displacement accuracy of the nano-displacement measurement system including intermodulation distortion error, cross-talk error, cross-polarization error and phase detection error are calculated. In the designed system, a He-Ne laser having three-longitudinal-mode is considered as the stabiliz...
