Quantum solid. In a quantum solid the dominant repulsive energy is the zero- point energy of the atoms. Consider a crude one-dimensional model of erystalline He' with each He atom confined to a line segment of length L. In the ground state the wave function within each segment is taken as a half wavelength of a free parti- cle. Find the zero-point kinetic energy per particle.
