Nature of problem:
Computer algebra implementation of the definition of a commutator, of commutator handling rules. Symbolic evaluation of unitary transformations for use in quantum dynamical problems.
Unitary transformations are represented by a truncated, finite series of nested commutators involving the generator. The maximum number of terms presently allowed in this series is 32. This can be extended by the user.
Uses an extension of Mathematica language offered by the package NCAlgebra. This must therefore be installed as a Mathematica add-on package.
