superop.m

Sided product superoperator in the spherical tensor basis set. Returns superoperators corresponding to right or left multiplication of a den-

Syntax

                     A=superop(spin_system,opspec,side)

Arguments

        opspec - Spinach operator specification described in Sections 2.1
                 and 3.3 of the following paper:
                        http://dx.doi.org/10.1016/j.jmr.2010.11.008
        side   - 'left' or 'right' causes the function to return a product
                 superoperator corresponding to a product from that side;
                 'comm' or 'acomm' results in commutation and anticommuta-
                 tion superoperator respectively.

Outputs

             A - a three-column array of row indices (first column),
                 column indices (second column) and values (third column).
    Note: this is a very general function to which direct calls are not
          usually required - please use the (much friendlier) operator()
          function.
    Note: the superoperator is returned in XYZ sparse format, which is
          different from Matlab's CSC format.
