Interacting particles in phase space

Husimi functions are employed in this project to study localization transitions as well as entangled spin-½ states. As a positive definite phase-space distribution, the Husimi function allows to quantitatively describe how strongly a quantum state is localized in phase space. The inverse participation ratio is particularly well suited to perform a disorder average in the case of localization transitions in disordered systems. For entangled states, a relation with the length of the concurrence vector is found.
