Snapshots of the outgoing wave packets at <em>t</em> = 3.4 μs Benedikt Herwerth Maarten DeKieviet Javier Madroñero Sandro Wimberger 10.6084/m9.figshare.1012090.v1 https://iop.figshare.com/articles/figure/_Snapshots_of_the_outgoing_wave_packets_at_em_t_em_3_4_s/1012090 <p><strong>Figure 2.</strong> Snapshots of the outgoing wave packets at <em>t</em> = 3.4 μs. Coordinate (in linear scale) and momentum distribution (in semilogarithmic scale) for a particle reflected on the oscillating surface (amplitude <em>d</em> = 4 nm) for different frequencies ω and fixed <em>x</em><sub>0</sub> = 4 <b>×</b> 10<sup>−10</sup> m (black curves). Red dashed lines: corresponding distributions for the static potential.</p> <p><strong>Abstract</strong></p> <p>We describe an experimentally realistic situation of the quantum reflection of helium atoms from an oscillating surface. The temporal modulation of the potential induces clear sidebands in the reflection probability as a function of momentum. These sidebands could be exploited to slow down atoms and molecules in the experiment.</p> 2013-06-27 00:00:00 modulation surface coordinate semilogarithmic scale figure abstract x 0 quantum reflection amplitude molecule helium atoms experiment reflection probability momentum distribution frequency situation nm wave packets function sideband snapshot Atomic Physics Molecular Physics
