Quantum Monte Carlo study of quasi-one-dimensional Bose gases
G. E. Astrakharchik, D. Blume, S. Giorgini +1
We study the behavior of quasi-one-dimensional (quasi-1d) Bose gases by Monte Carlo techniques, i.e., by the variational Monte Carlo, the diffusion Monte Carlo, and the fixed-node…

A Two-Atom Picture of Coherent Atom-Molecule Quantum Beats
Bogdan Borca, D. Blume, Chris H. Greene
A simple two-atom model is shown to describe a Bose-Einstein condensate of alkali atoms subjected to external magnetic field ramps near a Feshbach resonance. The implications uncov…
