First Principle Study of the Mechanical Properties and Phonon Dispersion of the Iron Pnictide Compound EuFe<sub>2</sub>As<sub>2</sub>

<div>The plotted phonon density of states. As the wavelength becomes longer, the frequency of the acoustic modes of vibration goes to zero, while for longer wavelengths in optical phonons, the frequency does not go to zero.</div>
