The area of trapping the atoms or molecules using light has advancedtremendously in the last few decades. In contrast, the idea of controlling (notonly trapping) the movement of atomic-sized particles using quantum mechanicalmatter waves is a completely new emerging area of particle manipulation. Thougha single previous report has suggested the pulling of atoms based on matterwave tractor beams, an attempt is yet to be made to produce a lateral force(moving the atoms towards left or right) using this technique. This articledemonstrates a matter wave-based manipulation scenario that gives rise toreversible lateral force on an atom due to the interaction energy of thequantum mechanical matter wave in the presence of a metal surface creating anasymmetrical set-up. For a symmetric set-up, no lateral force has beenobserved. We have performed several full wave simulations and analyticalcalculations on a particular set-up of Xenon scatterer atoms placed near aCopper surface, with two plane matter waves of Helium impinging in thedirection parallel to the surface from two sides of the scatterer. By solvingthe time-independent Schrodinger equation and using the solution, quantummechanical stress tensor formalism has been applied to compute the force actingon the particle. The full wave simulation results have been found in excellentagreement with the analytical calculations. The results for the adsorbedscatterer case suggests that our proposed technique can be an efficientcleaning procedure similar to electron-stimulated desorption for futuristicapplications.
