A practical guide to Terahertz imaging using thermal atomic vapour
Lucy Downes, Lara Torralbo-Campo, Kevin Weatherill
This tutorial aims to provide details on the underlying principles and methodologies of atom-based terahertz imaging techniques. Terahertz imaging is a growing field of research wh…
Observation of the motional Stark shift in low magnetic fields
Manuel Kaiser, Jens Grimmel, Lara Torralbo-Campo +5
We report on the observation of the motional Stark effect of highly excited Rb Rydberg atoms moving in the presence of a weak homogeneous magnetic field in a vapor cell. Emp…
Ionization spectra of highly Stark shifted rubidium Rydberg states
Jens Grimmel, Markus Stecker, Manuel Kaiser +4
We report on the observation and numerical calculation of ionization spectra of highly Stark-shifted Rydberg states of rubidium beyond the classical ionization threshold. In the nu…
Raman transitions between hyperfine clock states in a magnetic trap
J B Naber, L Torralbo-Campo, T Hubert +1
We present our experimental investigation of an optical Raman transition between the magnetic clock states of Rb in an atom chip magnetic trap. The transfer of atomic popula…
Measurement of Vacuum Pressure with a Magneto-Optical Trap: a Pressure-Rise Method
Rowan W. G. Moore, Lucie A. Lee, Elizabeth A. Findlay +3
The lifetime of an atom trap is often limited by the presence of residual background gases in the vacuum chamber. This leads to the lifetime being inversely proportional to the pre…
Light-induced atomic desorption in a compact system for ultracold atoms
Lara Torralbo-Campo, Graham D. Bruce, Giuseppe Smirne +1
In recent years, light-induced atomic desorption (LIAD) of alkali atoms from the inner surface of a vacuum chamber has been employed in cold atom experiments for the purpose of mod…
Magnetic-film atom chip with 10 m period lattices of microtraps for quantum information science with Rydberg atoms
V. Y. F. Leung, D. R. M. Pijn, H. Schlatter +11
We describe the fabrication and construction of a setup for creating lattices of magnetic microtraps for ultracold atoms on an atom chip. The lattice is defined by lithographic pat…
Holographic power-law traps for the efficient production of Bose-Einstein condensates
Graham D. Bruce, Sarah L. Bromley, Giuseppe Smirne +2
We use a phase-only spatial light modulator to generate light distributions in which the intensity decays as a power law from a central maximum, with order ranging from 2 (paraboli…
Smooth, holographically generated ring trap for the investigation of superfluidity in ultracold atoms
Graham D Bruce, James Mayoh, Giuseppe Smirne +2
We discuss the suitability of holographically generated optical potentials for the investigation of superfluidity in ultracold atoms. By using a spatial light modulator and a feedb…
