An effective scalar magnetic interaction for resonantly trapped atoms
Barry M. Garraway, Hélène Perrin
Atoms can be trapped using a combination of static and rotating magnetic fields. A theoretical analysis is performed of a rotating polarisation axis which is used to eliminate regi…
RF spectroscopy in a resonant RF-dressed trap
Raghavan Kollengode Easwaran, Laurent Longchambon, Paul-Eric Pottie +3
We study the spectroscopy of atoms dressed by a resonant radiofrequency (RF) field inside an inhomogeneous magnetic field and confined in the resulting adiabatic potential. The spe…
Influence of the Radio-Frequency source properties on RF-based atom traps
Olivier Morizot, Laurent Longchambon, Raghavan Kollengode Easwaran +5
We discuss the quality required for the RF source used to trap neutral atoms in RF-dressed potentials. We illustrate this discussion with experimental results obtained on a Bose-Ei…
Trapping and cooling of rf-dressed atoms in a quadrupole magnetic field
Olivier Morizot, Carlos L. Garrido Alzar, Paul-Eric Pottie +2
We observe the spontaneous evaporation of atoms confined in a bubble-like rf-dressed trap (Zobay and Garraway, 2001). The atoms are confined in a quadrupole magnetic trap and are d…
Agile low phase noise radio-frequency sine wave generator applied to experiments on ultracold atoms
Olivier Morizot, Julien De Lapeyre De Bellair, Fabrice Wiotte +3
We report on the frequency performance of a low cost (~500$) radio-frequency sine wave generator, using direct digital synthesis (DDS) and a field-programmable gate array (FPGA). T…
