Color-flavor transformation revisited
A talk in the Seminar Zufallsmatrizen series by
Martin Zirnbauer from Universität Köln
| Abstract: |
The "color-flavor transformation", conceived as a kind of
generalized Hubbard-Stratonovich transformation, is a variant
of the Wegner-Efetov supermatrix method for disordered
electron systems. Tailored to quantum systems with disorder
distributed according to the Haar measure of a compact Lie
group of any classical type (A, B, C, or D), it has been applied
to Dyson's Circular Ensembles, random-link network models,
quantum chaotic graphs, disordered Floquet dynamics, and
more. We review the method and, in particular, explore its
limits of validity. We also sketch a new alternative method to
treat models where the color-flavor transformation fails.
