The p=0 condensate is a myth
arXiv:1008.0240
Abstract
Analyzing some of the basic aspects of the dynamics of two bosons (interacting through a central force) and their importance in determining the ground state of a system like liquid , it is unequivocally concluded that our conventional belief in the existence condensate in the superfluid state of such systems [including the state of Bose Einstein condensate (BEC) of trapped dilute gases] is a myth.
