Condensate wavefunction
= Condensate wavefunction
{title2=$\psi(\mathbf r)$}
A <complex amplitude> describing a coherent condensate in <mean-field theory>. In the convention $\int|\psi|^2d^3r=N$, its squared modulus is the <condensate density>. Dividing by $\sqrt N$ gives a normalized orbital; formulas for interaction strengths and nonlinear terms must use the same normalization convention.
