Webphonons. From Table 1, θD is clearly large compared to the melting temperature (TM) in solid helium. In Debye’s model the zero point vibrational energy is (EZ)D = 2hKEiD = 9 8 θD. (2) This energy, a purely quantum effect, clearly dominates thermal energies (TM) so that solid helium may be called a quantum solid. From θD we may also
