主　　题：Bose Gas Phase Fluctuations 

摘      要：An elongated trap potential for cold atoms is designed based on a quadrupole-Ioffe *** fluctuations in a Bose-Einstein condensate(BEC),which is confined by the trap,are *** simulate the atom density distribution induced by fluctuation after time of flight from this elongated trap potential and study the temperature measurement method related to the ***,taking advantage of the tight confinement and radio frequency dressing technique,we propose a double well potential for splitting *** results are helpful for improving understanding of low-dimensional quantum gases and provide important guidance for atomic interferometry.
