 Cubic harmonic

In fields like computational chemistry and solid-state and condensed matter physics the so-called atomic orbitals, or spin-orbitals, as they appear in textbooks on quantum physics, are often partially replaced by cubic harmonics for a number of reasons.The formula_1 hydrogen-like atomic orbitals with principal quantum number formula_2 and angular momentum quantum number formula_3 are often expressed as

in which the formula_5 is the radial part of the wave function and formula_6 is the angular dependent part.
