Abstract
The dynamical nature of the motion of atoms in a silicon crystal is investi gated from the information theoretic standpoint with time series analysis a bout numerical solutions of molecular dynamics simulation. The atomic motio n exhibits exponential decay of information entropy with a characteristic t ime scale of similar to 40 x 10(-15) sec. This observation may be interpret ed as a signature of microscopic dynamical instability in solids.
