Determining $\mathbf{a}^*$, $\mathbf{b}^*$, and $\mathbf{c}^*$ for reciprocal unit cell [closed]
We are given a unit cell with $a=4$ angstroms, $b = 6$ angstroms, and $c=8$ angstroms. $\alpha=\beta= 90^{\circ}$, $\gamma= 120^{\circ}$.
I would like to find $\mathbf{a}^*$, $\mathbf{b}^{*}$, and $\m …

Determine Phase and Group Velocities for Monoatomic Lattice
I have a question about determining the phase and group velocity for a monoatomic lattice.
I know from various reference texts that
$$v_p = \frac {\omega}{q}$$
$$v_g = \frac {\partial \omega}{\partial …
