Atom interferometry with ultra-cold atoms
Summaries of Papers Presented at the Quantum Electronics and Laser Science Conference, 2003Summary form only given. Recent advances in the field of atom interferometry have opened the possibility of a new class of precise and accurate inertial force sensors. We have built laboratory prototypes of accelerometers, gravity gradiometers and gyroscopes based on atom interference principles which now perform at levels which compare favorably with ...

Cold antihydrogen atoms have been produced recently by mixing trapped antiprotons with cold positrons. The efficiency is remarkable: more than 10% of the antiprotons form antihydrogen. Future spectroscopy of antihydrogen has the potential to provide new extremely precise tests of the fundamental symmetry between matter and antimatter. In addition, cold

Photoassociation of Cold Ca Atoms
Physical Review Letters, 2000We present the first measurement of a photoassociative spectrum of an alkaline earth element near the dissociation limit. The observed spectrum of Ca2 formed from cold atoms shows the regular vibrational series with the characteristic spacing of the 1/R3 asymptotic potential.

Detection of weak magnetic fields with high spatial resolution is an important technology for various applications such as biological imaging, detection of MRI signals and fundamental physics. Cold atom magnetometry enables 10−11 T/\(\sqrt{\text{Hz}}\) sensitivities at the micron scale, that is, at the scale of a typical biological cell size.

Abstract In the previous two chapters we have investigated how resonant light beams interact with atomic transitions, and the way this process can be modified by means of cavities. We now wish to explore a different aspect of the light–matter interaction, namely light-induced forces.

Versatile cold atom target apparatus
Review of Scientific Instruments, 2012We report on a compact and transportable apparatus that consists of a cold atomic target at the center of a high resolution recoil ion momentum spectrometer. Cold rubidium atoms serve as a target which can be operated in three different modes: in continuous mode, consisting of a cold atom beam generated by a two-dimensional magneto-optical trap, in ...

Cold-atom scanning probe microscopy
Nature Nanotechnology, 2011Scanning probe microscopes are widely used to study surfaces with atomic resolution in many areas of nanoscience. Ultracold atomic gases trapped in electromagnetic potentials can be used to study electromagnetic interactions between the atoms and nearby surfaces in chip-based systems.

Abstract We employ ensembles of cold Rydberg-atom gases produced via photo-excitation of laser-cooled atom clouds in order to investigate collision-induced dynamics, excitation blockades, and Rydberg-atom trapping. After a general description of typical experimental methods used in this research, we review state-mixing and ionizing collision ...
