We present quantitative measurements of the spatial density profile of Bose-Einstein condensates of sodium atoms confined in a 4-Dee magnetic bottle. The condensates are imaged in transmission with near-resonant laser light. We demonstrate that the Thomas-Fermi surface of a condensate can be determined to better than 1%. More generally, we obtain excellent agreement with mean-field theory. We conclude that precision measurements of atomic scattering lengths and interactions between phase…

Two-gas description of dilute Bose-Einstein condensates at finite temperature
We show that recent treatments of magnetically trapped Bose-Einstein condensates (BECs) at temperature T>0 fit a simple picture: the condensate wavefunction is that of a T = 0 BEC with the
Bose–Einstein condensation has been realized as dilute atomic vapors. This achievement has generated immense interest in this field. This article review of recent theoretical research into the
Quantum fluctuations in the image of a Bose gas
We analyze the information content of density profiles for an ultracold Bose gas of atoms and extract resolution limits for observables contained in these images. Our starting point is density
Possibility of an Optically-Trapped Bose-Einstein Condensation
We propose a novel gravito-optical atom trap composed of a blue-detuned, conical dark-hollow-beam propagating upward and the gravity field. When cold atoms are loaded into the conical
Buffer-gas cooled Bose-Einstein condensate.
We report the creation of a Bose-Einstein condensate using buffer-gas cooling, the first realization of Bose-Einstein condensation using a broadly general method which relies neither on laser cooling
Dynamics of Quenched Ultracold Quantum Gases
Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned
Mean-field regime and Thomas–Fermi approximations of trapped Bose–Einstein condensates with higher-order interactions in one and two dimensions
We derive rigorously one- and two-dimensional mean-field equations for cigar- and pancake-shaped Bose–Einstein condensates (BECs) with higher-order interactions (HOIs), which originate from
Bose–Einstein Condensation in a Dilute, Trapped Gas at Positive Temperature
We consider an interacting, dilute Bose gas trapped in a harmonic potential at a positive temperature. The system is analyzed in a combination of a thermodynamic and a Gross–Pitaevskii (GP) limit


Laser cooling and trapping of atoms
 A detailed experimental and theoretical investigation of a magneto-optical trap for caesium atoms is presented. Particular emphasis has been placed on achieving high spatial number densities and
Introduction to Fourier optics
The second edition of this respected text considerably expands the original and reflects the tremendous advances made in the discipline since 1968. All material has been thoroughly updated and
Quantum methods with Mathematica
This book is a work designed for computer interaction in an upper-division undergraduate or first-year graduate quantum mechanics course and is also a toolbox for the practicing physicist seeking to automate a variety of algebraic and numerical tasks with the computer.
