Some Comments on Bose–Einstein Condensation

Wei Xiao

The principle of Bose\|Einstein Condensation(BEC) is outlined.The great contribution of E.A.Connell,C.E.Wieman and W.Ketterle who shared the 2001 Nobel Prize in Physics,in creating the world's first Bose\|Einstein Condensate is described.New progress in their studies of BEC physics and atomlasers is reviewed,as well as further prospects of for the applications of BEC.

We discuss the comment [ arXiv:1102.2943] by E. Kozik about "Dispersive bottleneck delaying thermalization of turbulent Bose-Einstein Condensates [arXiv:1007.4441]".

A critique is presented of a recent comment by March in which he argues that the Bose–Einstein condensate may not exist in HeII. It is concluded that such a dramatic statement is not warrranted in the light of current evidence.
