Trapping atoms with radio-frequency adiabatic potentials
Hélène Perrin, Barry M. Garraway
In this chapter we review the field of radio-frequency dressed atom trapping. We emphasise the role of adiabatic potentials and give simple, but generic models of electromagnetic f…
Non-adiabatic losses from radio-frequency dressed cold atom traps: beyond the Landau-Zener model
Kathryn A Burrows, Barry M Garraway, Hélène Perrin
Non-adiabatic decay rates for a radio-frequency dressed magnetic trap are calculated using Fermi's Golden Rule: that is, we examine the probability for a single atom to make transi…
Detailed study of a transverse field Zeeman slower
Dany Ben Ali, Thomas Badr, Thibault Brézillon +3
We present a thorough analysis of a Zeeman slower for sodium atoms made of permanent magnets in a Halbach configuration. Due to the orientation of the magnetic field, the polarisat…
Inductive dressed ring traps for ultracold atoms
Matthieu Vangeleyn, Barry M. Garraway, Hélène Perrin +1
We present two novel dressed inductive ring trap geometries, ideal for atom interferometry or studies of superfluidity and well-suited to utilisation in atom chip architectures. Th…
Evaporative cooling in a radio-frequency trap
Carlos L. Garrido Alzar, Hélène Perrin, Barry M. Garraway +1
A theoretical investigation for implementing a scheme of forced evaporative cooling in radio-frequency (rf) adiabatic potentials is presented. Supposing the atoms to be trapped by…
Diffuse reflection of a Bose-Einstein condensate from a rough evanescent wave mirror
Helene Perrin, Yves Colombe, Brigitte Mercier +2
We present experimental results showing the diffuse reflection of a Bose-Einstein condensate from a rough mirror, consisting of a dielectric substrate supporting a blue-detuned eva…
