TL;DR
This paper investigates quantum reflection of helium atoms from an oscillating surface, showing how surface modulation creates sidebands in reflection probability that could be used to control atomic motion.
Contribution
It introduces a realistic model of quantum reflection involving an oscillating surface and demonstrates the emergence of sidebands in reflection probability.
Findings
Sidebands appear in reflection probability due to surface oscillation
Modulation can be used to slow down atoms and molecules
Experimental setup for observing quantum reflection with oscillating surfaces
Abstract
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. Theses sidebands could be exploited to slow down atoms and molecules in the experiment.
