Low-dimensional Bose-einstein Condensation under External Potential
Liu Chuan-yong
Abstract
The discussion is made on the relation between the state density of systems and the dimensionality of Bose-Einstein Condensation(BEC),with the further stress laid on the analysis of low dimensional BEC under the influence of power-law potential and harmonic potential.The result is the non-production of low dimensional BEC with no external potential and the production of one-dimensional and two-dimensional BEC under the power of external potential.
