Effective Field Theory for Atom-Molecule Systems III: Dynamic Effects of a Feshbach Resonance on Bragg scattering from a Bose-Einstein Condensate
Catarina E. Sahlberg, R. J. Ballagh, C. W. Gardiner
We present a theoretical model for Bragg scattering from a Bose-Einstein condensate (BEC) in the vicinity of a magnetic Feshbach resonance, using a two c-field formalism, one c-fie…
Effective Field Theory for Atom-Molecule Systems II: Stationary Solutions and Bogoliubov Excitations in Atom-Molecule Systems
Catarina E Sahlberg, C W Gardiner
We formulate the basic theoretical methods for Bose-Einstein Condensation of atoms close to a Feshbach resonance, in which the tunable scattering length of the atoms is described u…
Effective Field Theory for Atom-Molecule Systems I: Formulation of Effective Field Theory
Catarina E Sahlberg, C W Gardiner
We present a model of a coupled bosonic atom-molecule system, using the recently developed c-field methods as the basis in our formalism. We derive expressions for the s-wave scatt…
Theory of coherent Bragg spectroscopy of a trapped Bose-Einstein condensate
P. B. Blakie, R. J. Ballagh, C. W. Gardiner
We present a detailed theoretical analysis of Bragg spectroscopy from a Bose-Einstein condensate at T=0K. We demonstrate that within the linear response regime, both a quantum fiel…
Growth of Bose-Einstein Condensates from Thermal Vapor
M. Köhl, M. J. Davis, C. W. Gardiner +2
We report on a quantitative study of the growth process of Rb Bose-Einstein condensates. By continuous evaporative cooling we directly control the thermal cloud from which t…
Quantum kinetic theory VII: The influence of vapor dynamics on condensate growth
M. J. Davis, C. W. Gardiner, R. J. Ballagh
We extend earlier models of the growth of a Bose-Einstein condensate to include the full dynamical effects of the thermal cloud by numerically solving a modified quantum Boltzmann…
