The time-dependent variational principle proposed by Balian and Ve ne roni is used to provide an optimal value of the generating functional for the multi-time Green's functions of a set of bosonic observables Q + . By restricting the two trial quantities to gaussian operators, an explicit formula is
The computer program allows to calculate the Green's function of a three-dimensional system with two-dimensional translation symmetry. Examples for its application are the crystal surface and the interface between two crystals. The crystal can be composed from rumpled atomic layers, that is, the ato
