Abstract | ||||
In this article a study of the specific heat, energy fluctuation and entropy of 1D, 2D, 3D harmonic and 1D anharmonic oscillators is presented. The effect on the thermodynamic properties of considering a finite number of the quantum states, involved in evaluating the partiton function, is analyzed. In the case of the anharmonic oscillator we calculate the contribution of the anharmonicity to these properties and compare ( or contrast) with their counterparts in the harmonic case. | ||||
