It is pointed out that the thermal expansion coefficient of solids is not always zero even in ideally harmonic crystals, if one quantizes the phonon field. This apparently differs from the customary treatment which is essentially based on non-quantized phonon field model. Our discussion which starts
A parameter-free model based on molecular mechanics with zero Kelvin potentials is developed to describe quantitatively the shortening of the unit cell of polyethylene crystals in chain direction with increasing temperature. Based on the well-known conception that an increase of the amplitudes of th
