摘要：

We present analytic and numerical studies of the order-parameter distribution function near the critical point of O(n) symmetric three-dimensional (3D) systems in a finite geometry. The distribution function is calculated within the rho(4) field theory for a 3D cube with periodic boundary conditions by means of a new approach that appropriately deals with the Goldstone modes below T-c. Good agreement is found with new Monte Carlo data for the distribution function of the magnetization of the 3D XY (n = 2) and Heisenberg (n = 3) models.
