  • What happens if we investigate the simple harmonic oscillator problem $V(\mathbf x)=c|\mathbf x|^2$? This potential is exactly of the form discussed in the previous paragraph and has hyper spherical -symmetry. Oone may want to use a large spherical domain with a large +symmetry. One may want to use a large spherical domain with a large outer radius, to approximate the whole-space problem (say, by invoking GridGenerator::hyper_ball). +
  • The plots above show the wave function $\Psi(\mathbf x)$, but the +physical quantity of interest is actually the probability density +$|\Psi(\mathbf x)|^2$ for the particle to be at location $\mathbf x$. +Some visualization programs can compute derived quantities from the data in +an input file, but we can also do so right away when creating the output +file. The facility to do that is the DataPostprocessor class that can +be used in conjunction with the DataOut class. Examples of how this +can be done can be found in @ref step_29 "step-29" and +@ref step_33 "step-33". +
  • What happens if the particle in the box has internal degrees of freedom? For example, if the particle were a spin-$1/2$ particle? In that case, we may want to start solving a vector-valued problem -instead.
