# Use of real Dirac matrices in two-dimensional coupled linear optics

@article{Baumgarten2011UseOR, title={Use of real Dirac matrices in two-dimensional coupled linear optics}, author={Christian Baumgarten}, journal={Physical Review Special Topics-accelerators and Beams}, year={2011}, volume={14}, pages={114002} }

The Courant-Snyder theory for two-dimensional coupled linear optics is presented, based on the systematic use of the real representation of the Dirac matrices. Since any real $4\times 4$-matrix can be expressed as a linear combination of these matrices, the presented Ansatz allows for a comprehensive and complete treatment of two-dim. linear coupling. A survey of symplectic transformations in two dimensions is presented. A subset of these transformations is shown to be identical to rotations…
