Query: Correlation functions for a strongly correlated boson system   The correlation functions for a strongly correlated exactly solvable
one-dimensional boson system on a finite chain as well as in the thermodynamic
limit are calculated explicitly. This system which we call the phase model is
the strong coupling limit of the integrable q-boson hopping model. The results
are presented as determinants.
