Phonon dispersion of an bcc 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} = $  

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

$\hspace{0.2cm} \Gamma\hspace{3.9cm} H \hspace{3.5cm} P \hspace{3.5cm} \Gamma \hspace{2.8cm} N$



 $\Gamma: 0,0,0$ 

$H: 0,0,\frac{2\pi}{a}$

$P: \frac{\pi}{a},\frac{\pi}{a},\frac{\pi}{a}$

$N: 0,\frac{\pi}{a},\frac{\pi}{a}$
