Mean-field description of collapsing and exploding Bose-Einstein condensates
(2002-07-01)
Numerical simulations based on the time-dependent mean-field Gross-Pitaevskii equation was performed to explain the dynamics of collapsing and exploding Bose-Einstein condensates (BEC) of 85Rb atoms. The atomic interaction ...

Influence of beam collimation on fast-atom diffraction studied via a semiquantum approach
(American Physical Society, 2015-12)
The influence of the collimating conditions of the incident beam on diffraction patterns produced by grazing scattering of fast atoms off crystal surfaces is studied within a semiquantum approach, called the surface initial ...
Surface-grating deflection of fast atom beams
(American Physical Society, 2013-07)
For energetic atomic beams grazingly incident at the surface along the low index directions, fast motion parallel to the surface and slow motion perpendicular to the surface lead to the quantum diffraction pattern in the ...
Forced oscillations with continuum models of atomic force microscopy
(2012-12-01)
The dynamics of the AFM-atomic force microscope follows a model based in a Timoshenko cantilever beam with a tip attached at the free end and acting with the surface of a sample. General boundary conditions arise when the ...
Single- and double-slit collimating effects on fast-atom diffraction spectra
(Elsevier Science, 2016-04-02)
Diffraction patterns produced by fast He atoms grazingly impinging on a LiF(001) surface are investigated focusing on the influence of the beam collimation. Single- and double-slit collimating devices situated in front of ...
