Studies of the Hydrodynamic Properties of Bose-Einstein Condensate of⁸⁷Rb Atoms in a Magnetic Trap

Abstract

We report details of the apparatus and the experimental procedure leading to production of the Bose-Einstein condensate of 87 Rb atoms. Basic hydrodynamic properties of the condensate, like quadrupole oscillations and free fall expansion, are investigated. They provide also characteristics of the magnetic trap crucial for interpretation of future experiments.

Free-fall expansion of finite-temperature Bose–Einstein condensed gas in the non-Thomas–Fermi regime

“…This sample is analysed by absorptive imaging with the imaging beam resonant with the |F = 2, m F = 2 -|F = 3, m F = 3 hfs component of the 87 Rb D2 line. More experimental details can be found in [21].…”

Analysis and calibration of absorptive images of Bose–Einstein condensate at nonzero temperatures

“…In this Section we discuss results of the analysis of the typical experimental images obtained with our setup [22]. The experiment was devoted to studies of the free-fall dynamics of a finite-temperature condensate of 87 Rb in the F=2 state and is described in more detail elsewhere [23].…”

Magneto-optical Trap: Fundamentals and Realization

“…They are used e.g. for preliminary cooling in the Bose-Einstein condensation [17][18][19]. In recognition of their pioneering achievements in the cooling and trapping of atoms in 1997, C. Cohen-Tannoudji, S. Chu and W. Phillips were awarded the Nobel Prize [20].…”
