Structural properties and energetics of diffuse 87Rb clusters in three-dimension.
TLDR
The motivation of the present study is to investigate the possibility of formation of N-body clusters interacting through the van der Waals interaction, and compare the system with the well studied He, Ne, and Ar clusters.Abstract:
A correlated two-body basis function is used to describe the three-dimensional bosonic clusters interacting via two-body van der Waals potential. We calculate the ground state and the zero orbital angular momentum excited states for RbN clusters with up to N = 40. We solve the many-particle Schrodinger equation by potential harmonics expansion method, which keeps all possible two-body correlations in the calculation and determines the lowest effective many-body potential. We study energetics and structural properties for such diffuse clusters both at dimer and tuned scattering length. The motivation of the present study is to investigate the possibility of formation of N-body clusters interacting through the van der Waals interaction. We also compare the system with the well studied He, Ne, and Ar clusters. We also calculate correlation properties and observe the generalised Tjon line for large cluster. We test the validity of the shape-independent potential in the calculation of the ground state energy o...read more

Observation of Resonance Condensation of Fermionic Atom Pairs
TL;DR: In order to search for condensation on either side of the resonance, a technique that pairwise projects fermionic atoms onto molecules is introduced; this enables to measure the momentum distribution of fermionics atom pairs.
