摘要
The critical temperature of Bose-Einstein condensation at minimum momentum state for weakly interacting Bose gases in a power-law potential and the deviation of the critical temperature from ideal bose gas are studied.The effect of interaction on the critical temperature is ascribed to the ratiaoα/I_(c),whereαis the scattering length for s wave andI_(c) is de Broglie wavelength at critical temperature.Asα/I_(c)<<1/(2p)^(2),the interaction is negligible.The presented deviation of the critical temperature for three dimensional harmonI_(c) potential is well in agreement with recent measurement of critical temperature for ^(87)Rb bose gas trapped in a harmonI_(c) well.
