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