The package has been updated for compatibility with Mathematica 12.
It is intended to be both general and user-friendly, and to be useful to the working physicist as well as to students.ĪtomicDensityMatrix is open source software, licensed under the GPLv3. AtomicDensityMatrix is a package for Mathematica 6 and later that facilitates analytic and numerical density-matrix calculations in atomic and related systems.
