Phase fluctuations of a d-wave superconducting order parameter are theoretically studied in the context of high-T<Subscript>c</Subscript> cuprates. We consider an extended t-J model describing electrons in a layer which also contains long-range Coulomb interactions. The constraint of having at most singly occupied...</subscript>
