Simultaneous Precision Gravimetry and Magnetic Gradiometry with a Bose-Einstein Condensate: A High Precision, Quantum Sensor.
A Bose-Einstein condensate is used as an atomic source for a high precision sensor. A 5×10^{6} atom F=1 spinor condensate of ^{87}Rb is released into free fall for up to 750 ms and probed with a T=130 ms Mach-Zehnder atom interferometer based on Bragg transitions. The Bragg interferometer simultaneously addresses the three magnetic states |m_{f}=1,0,-1⟩, facilitating a simultaneous measuremen...
متن کاملHigh visibility gravimetry with a Bose-Einstein condensate
A Bose-Einstein condensate (BEC) is frequently described as the matter-wave analog of an optical laser – the preferred source for optical interferometry. In this project, we have demonstrated an atom interferometer-based gravimeter using a Rb Bose-condensed source [1]. Our data represent the highest fringe visibility yet achieved in such a device (Fig. 1), for both standard, and large-momentum-...
متن کاملQuantum instability of a Bose-Einstein condensate with attractive interaction.
We study the quantum and the mean-field Gross-Pitaevskii (GP) dynamics of a Bose-Einstein condensate gas confined in a toroidal trap. According to GP, if the interatomic interaction is attractive, the rotational states of the system can be dynamically stable or unstable depending on the strength of the mean-field energy. The full quantum analysis, however, reveals that the condensate is always ...

متن کاملSolitons for nearly integrable bright spinor Bose-Einstein condensate
Using the explicit forms of eigenstates for linearized operator related to a matrix version of Nonlinear Schrödinger equation, soliton perturbation theory is developed for the $F=1$ bright spinor Bose-Einstein condensates. A small disturbance of the integrability condition can be considered as a small correction to the integrable equation. By choosing appropriate perturbation, the soli...
