Quantum statistics of a forced harmonic oscillator acted upon by a time-dependent external force are derived usingthe Wilcox trick and the time-dependent inhomogeneous Bogoliubov transformation formalism. The internal energy, fluctuation of the particle-number average and entropy of this nonequilibrium system are presentedexplicitly.
