Title: Effect of projection velocity and temperature on the reflection of ultracold atoms from a periodic one-dimensional corrugated magnetic potential
Author(s): Singh, Mandip; Hannaford, Peter
Abstract: The spatial profile of ultracold atoms reflecting from an exponentially decaying magnetic potential depends on parameters such as the corrugation in the magnetic potential and the temperature of the atomic cloud. We report on experimental investigations of the effect of projection velocity which determines the strength of the interaction of the atom cloud with the magnetic potential and the effect of temperature of ultracold Rb-87 atoms reflecting from a periodic one-dimensional corrugated magnetic potential. The magnetic potential is generated on an atom chip by a periodic permanent magnetic structure of period 10 μm. The amplitude of the corrugation is controlled by applying a uniform external-bias magnetic field.
