| A system of charged weakly interacting bosons with "d" symmetry is considered. The interaction U(d) = U(s) f(θ) contains the angle dependence f(θ) ~ |Y2,1|2 consistent with "d" symmetry. This system resembles much more free bosons than the system with "s" symmetry (interaction U(s)). For example at T=0, n ≈ nc(d), where n, nc(d) are the densities of particles and condensate respectively. |
