 The Project DiracQ:

We present a software package DiracQ for simplifying certain calculations that arise in quantum many body physics. It is designed for helping with algebraic manipulations that arise in typical in quantum Condensed matter Physics and Nuclear Physics problems, and in some subareas of Chemistry. DiracQ is invoked within a Mathematica session, and extends the symbolic capabilities of Mathematica in many ways. It enables the user to carry out quantum mechanical calculations with various kinds of operators, either spin operators, Bose and Fermi operators defined on a discrete lattice, or the position and momentum operators in the continuum.
