Spin Quantum Hall Effect: the Critical Exponents
Hrant Topchyan, Win Nuding, Andreas Klümper +1
The spin quantum Hall effect (SQHE) provides one of the few examples of an Anderson localization transition for which exact critical exponents are known, making it an important tes…

Exact spectral function and nonequilibrium dynamics of the strongly interacting Hubbard model
Ovidiu I. Patu, Andreas Klumper, Angela Foerster
Analytical results on the correlation functions of strongly correlated many-body systems are rare in the literature and their importance cannot be overstated. We present determinan…

Managing Singular Kernels and Logarithmic Corrections in the Staggered Six-Vertex Model
Mouhcine Azhari, Andreas Klümper
In this paper, we investigate the spectral properties of the staggered six-vertex model with symmetry for arbitrary system sizes using non-linear integral equation…
