According to the Mermin-Wagner theorem, not under equilibrium conditions.

[tex]N_0 = \left (1-\left (\frac{T}{T_c}\right )^2\right )N[/tex]

Where [tex]N_0[/tex] is the number of the particles in the ground state, and N the total number of particles.

Don't know what this Mermin-Wagner theorem says about it. To be honest, never even heared of that theorem :)
