Superbosonization formula and its application to random matrix theory
J. E. Bunder, K. B. Efetov, V. E. Kravtsov +2
Starting from Gaussian random matrix models we derive a new supermatrix field theory model. In contrast to the conventional non-linear sigma models, the new model is applicable for…
Energy correlations for a random matrix model of disordered bosons
T. Lueck, H. -J. Sommers, M. R. Zirnbauer
Linearizing the Heisenberg equations of motion around the ground state of an interacting quantum many-body system, one gets a time-evolution generator in the positive cone of a rea…
Localization from sigma-model geodesics
A. Lamacraft, B. D. Simons, M. R. Zirnbauer
We use a novel method based on the semi-classical analysis of sigma-models to describe the phenomenon of strong localization in quasi one-dimensional conductors, obtaining the full…
Another critique of the replica trick
Martin R. Zirnbauer
Kamenev and Mezard, and Yurkevich and Lerner, have recently shown how to reproduce the large-frequency asymptotics of the energy level correlations for disordered electron systems,…
