Spatial Correlations in Bose Gases

Spatial Correlations in Bose Gases

We calculate energies, condensate fractions and two-body correlation functions for a system of N identical bosons in a trap. Both attractive and repulsive finite-range interactions with a large range of positive scattering lengths are used. At small scattering lengths the system is model independent...

Zusammenfassung:We calculate energies, condensate fractions and two-body correlation functions for a system of N identical bosons in a trap. Both attractive and repulsive finite-range interactions with a large range of positive scattering lengths are used. At small scattering lengths the system is model independent. When the scattering length is comparable to the trap length the properties of the system depend on the details of the interaction.
