Impurity Dynamics in a Bose Condensate
Siu A. Chin, Harald Forbert
We estimate the changes in the condensate ground state energy induced by one or more "sizable" impurities. By "sizable", we mean an impurity whose size is within a few orders of ma…

Fermionic and Bosonic Bubbles and Foam
Aurel Bulgac, Siu A. Chin, Harald A. Forbert +2
The positioning of one or more bubbles inside a many fermion or boson system, does not affect the volume, surface or curvature terms in the liquid drop expansion of the total energ…

Impurity Expulsion From a Bose-Einstein Condensate
Siu A. Chin, Harald A. Forbert
When a sizable, hard-sphere-like impurity is placed in a trapped Bose-Einstein condensate, it will create a hole in the condensate wave function. Since it costs more energy to dril…
