 +###
 +The kubic harmonics (also known as cubic harmonics) are linear combinations of the spherical harmonics and irreducible representations of the cubic ($O_h$) point group. For $s$, $p$ and $d$ wave-functions the kubic harmonics are besides a different order the same as the tesseral harmonics. For higher angular momentum they are different. 
 +###
 +
 +###
 +The relation between the kubic harmonics and the tesseral harmonics is given by the matrix $T_{Z\,\mathrm{to}\,K}$, whereby the vector $\{Z_{l}^{(m=-l)},K_{l}^{(m=-l+1)},\dots,K_{l}^{(m=l)}\}$ is given as $T_{Z\,\mathrm{to}\,K} \cdot \{Y_{l}^{(m=-l)},Y_{l}^{(m=-l+1)},\dots,Y_{l}^{(m=l)}\}$. Explicit forms of $T_{Z\,\mathrm{to}\,K}$ for $l$ equal or smaller to 6 are:

 +The following table shows the kubic harmonics up to $l=6$. We list the explicit function in terms of the directional cosines $x$, $y$ and $z$. The plots show the surface defined by the equation $r={K_l^{(m)}}^* K_l^{(m)}$. The color of the surface is according to the phase with red for positive and cyan for negative. We show a 3D image as well as a projection along the $x$, $y$ and $z$ direction.
