GOGeneralPositionIreps

GOGeneralPositionIreps

is an option which controls if the character table and representation matrices of the full space group or the character table of the space group of k is printed.

Details and Options

  • This option is used by GTSGGetIreps and GTSGCharacterTable.
  • See: W. Hergert, M. Geilhufe, Group Theory in Solid State Physics and Photonics. Problem Solving with Mathematica

Examples

Basic Examples  (1)

  • First load the package.
  • We choose the monoclinic space group P21/c (#14). We first specify the monoclinic basis vectors and calculate the corresponding basis vectors of the reciprocal lattice using GTReciprocalBasis. Then we install the space groups using GTInstallGroup.

    • If GOGeneralPositionIreps->False is specified, only the characters and matrices of the group of the wave vector k are given.

    If GOGeneralPositionIreps->True is specified, the characters of the full space group for the wave vector k are given.
