Separated-path ramsey atom interferometer

Abstract:

We demonstrate a novel type of cesium atom interferometer which uses a combination of a microwave ground state transition and momentum changing adiabatic transfer light pulses as the atom optical components. It is the first atom interferometer where the mechanism which forms the internal superposition plays no part in spatially splitting the atomic wave packets. The coherence length of the atom source is found by measuring the spatial correlation between the two interferometer arms. This allows us to determine the temperature of the atomic ensemble. © 1998 The American Physical Society.

Atomic dipole trap formed by a Gaussian standing wave

P SOC PHOTO-OPT INS 3580 (1998) 102-110

Authors:

P Zemanek, CJ Foot

Abstract:

We suggest an atomic dipole trap which is produced by two counter-propagating Gaussian beams with different waists. This set-up creates an intensity dip in axial and radial directions near the node of the standing wave and can be used as an atom trap for blue detuning of the light. We simulated the behaviour of two level atoms in this trap using the dressed state Monte-Carlo method and we show that it gives a goad trapping when the residual intensity at the bottom of traps is small.
