**Energy fluctuations in one-dimensional crystal**D.V. Tsvetkov (programming), A.M. Krivtsov (analytical silution)

This program demonstrates the fluctuations in the kinetic, potential, and full energy in the one-dimensional crystal. Fluctuations of the kinetic energy described by the following equation:

where

— Bessel function of the first kind at 0, — is the stiffness of the interparticle bond, — is the particle mass.Error in widget Iframe: unable to write file /var/www/mech1273/extensions/Widgets/compiled_templates/wrt59c11ce687571
