Breaking the Spin Degeneracy for Distributions of Off-Diagonal Scattering Matrix Elements in the Case of Symplectic Symmetry
Nils Gluth, Thomas Guhr
Recently derived exact expressions for the distributions of scattering matrix elements show that all combinations of ingoing and outgoing spin orientations are equally distributed.…
Influence of Time Reversal Invariance Breaking on the Distribution of Off-Diagonal Scattering Matrix Elements and Cross Sections
Nils Gluth, Ahmed Aldabag, Thomas Guhr
Scattering theory is a key tool for the investigation of quantum systems. Universal approaches are of interest, particularly in the framework of Random Matrix Theory. Dyson's Three…
Distribution of Scattering Matrix Elements in the case of Symplectic Symmetry
Nils Gluth, Thomas Guhr
Scattering theory is at the core of gaining information about most quantum systems. In general, analytic progress is difficult and the investigation of universal features using sta…
Random Matrices and the Free Energy of Ising-Like Models with Disorder
Nils Gluth, Thomas Guhr, Alfred Hucht
We consider an Ising model with quenched surface disorder, the disorder average of the free energy is the main object of interest. Explicit expressions for the free energy distribu…
