Dynamical instability of the motion of atoms in a silicon crystal.
The dynamical nature of the motion of atoms in a silicon crystal is investigated from the information theoretic standpoint with time series analysis about numerical solutions of molecular dynamics simulation. The atomic motion exhibits exponential decay of information entropy with a characteristic time scale of approximately 40 x 10(-15) sec. This observation may be interpreted as a signature of microscopic dynamical instability in solids.
