Exponentially decaying correlations in a gas of strongly interacting spin-polarized 1D fermions with zero-range interactions
Scott A. Bender, Kevin D. Erker, Brian E. Granger
We consider the single particle correlations and momentum distributions in a gas of strongly interacting spinless 1D fermions with zero-range interactions. This system represents a…
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…
Quasi-one-dimensional Bose gases with large scattering length
G. E. Astrakharchik, D. Blume, S. Giorgini +1
Bose gases confined in highly-elongated harmonic traps are investigated over a wide range of interaction strengths using quantum Monte Carlo techniques. We find that the properties…
Tuning the interactions of spin-polarized fermions using quasi-one-dimensional confinement
Brian E. Granger, D. Blume
The behavior of ultracold atomic gases depends crucially on the two-body scattering properties of these systems. We develop a multichannel scattering theory for atom-atom collision…
