Hyperbolic Hubbard-Stratonovich transformation made rigorous

Y. V. Fyodorov, Y. Wei, M. R. Zirnbauer

We revisit a long standing issue in the theory of disordered electron systems and their effective description by a non-linear sigma model: the hyperbolic Hubbard-Stratonovich (HS)…

Character expansion method for supergroups and extended superversions of the Leutwyler-Smilga and Berezin-Karpelevich integrals

C. Lehner, T. Wettig, T. Guhr +1

We introduce an extension of the character expansion method to the case of supergroups. This method allows us to calculate a superversion of the Leutwyler-Smilga integral which, to…
