Rescaled and shifted energy distribution ρ(<em>z</em>) of the reflected particle for the same parameters as in the previous figure Benedikt Herwerth Maarten DeKieviet Javier Madroñero Sandro Wimberger 10.6084/m9.figshare.1012091.v1 https://iop.figshare.com/articles/figure/_Rescaled_and_shifted_energy_distribution_em_z_em_of_the_reflected_particle_for_the_same_parameters_/1012091 <p><strong>Figure 3.</strong> Rescaled and shifted energy distribution ρ(<em>z</em>) of the reflected particle for the same parameters as in the previous figure. The distribution is computed from the momentum distribution for positive momenta <em>k</em> only (see figure <a href="http://iopscience.iop.org/0953-4075/46/14/141002/article#jpb473836f2" target="_blank">2</a>). For each value of ω, the peaks occur at integer values of z=n \in \mathbb {N}, cf equation (<a href="http://iopscience.iop.org/0953-4075/46/14/141002/article#jpb473836eqn07" target="_blank">7</a>).</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 figure momenta k reflection probability momentum distribution integer values helium atoms sideband quantum reflection Atomic Physics Molecular Physics
