Phonon dispersion of an simple cubic crystal

The code from the previous page can be put in a loop to calculate the dispersion relation as a function of $k$.

$\frac{C_2}{C_1} = $  

$\sqrt{\frac{M}{C_1}}\omega$

$\hspace{0.3cm}\Gamma\hspace{2.6cm} X \hspace{2.6cm} M \hspace{3.8cm} \Gamma \hspace{4.5cm} R$



 $\Gamma: 0,0,0$ 

$X: \pi/a,0,0$

$M: \pi/a,\pi/a,0$

$R: \pi/a,\pi/a,\pi/a$
