The method of the effective action for the composite operators Φ2(x) and Φ4(x) is applied to the thermodynamics of the scalar quantum field with λΦ4 interaction. An expansion of the finite temperature effective potential in powers of ℏ provides successive approximations to the free energy with an effective mass and an effective coupling determined by the gap equations. The numerical results are studied in the spacetime of one dimension when the theory is equivalent to the quantum mechanics of an anharmonic oscillator. The approximations to the free energy show quick convergence to the exact result.
