We report on the realization of Bose-Einstein condensation of metastable helium-4. After exciting helium to its metastable state in a novel pulse-tube cryostat source, the atomic beam is collimated and slowed. We then trap several 10^8…

Results of identical pion correlations from the first year of data collection with the PHENIX detector at RHIC (\snn=130GeV) are presented. PHENIX has good particle identification using an electromagnetic calorimeter for timing, leading to…

We consider the possibility that dark matter halos are made of quantum particles such as fermions or bosons in the form of Bose-Einstein condensates. In that case, they generically have a "core-halo" structure with a quantum core that…
