Matter-Wave Optics and Interferometry with Laser-Cooled Atomsd to slow, deflect, compress, cool and trap atoms; thus creating either nearly monochromatic atomic beams or atom clouds almost at rest, both of high densities and with de Broglie wavelengths up to several hundred nanometers. These ensembles show sufficient spatial and temporal coherence to exhibit matter wave interference and diffraction.小步舞 发表于 2025-3-25 23:10:08

Bragg Scattering of a Coherent Ultracold Atomic Beam in Nonlinear Atom OpticsIn the Bragg resonance regime, the standing wave laser acts as a nonlinear atomic beam splitter. The atomic nonlinearity is due to the dipole-dipole interaction between ultracold atoms which leads to self-phase and cross-phase modulation and two-wave mixing of the scattered atomic waves in the Bragg resonance regime.sterilization 发表于 2025-3-26 13:36:41
