Visualizing the multifractal wavefunctions of a disordered two-dimensional electron gas
Berthold Jäck, Fabian Zinser, Elio J. K\" onig +5
The wavefunctions of a disordered two-dimensional electron gas at the quantum-critical Anderson transition are predicted to exhibit multifractal scaling in their real space amplitu…

Renormalization group analysis for the quasi-1D superconductor BaFeS
Elio J. König, Alexei M. Tsvelik, Piers Coleman
Motivated by the discovery of superconductivity in the two-leg, quasi-one dimensional ladder compound, BaFeS we present a renormalization group study of electrons moving on…

Universal fidelity near quantum and topological phase transitions in finite 1D systems
E. J. König, A. Levchenko, N. Sedlmayr
We study the quantum fidelity (groundstate overlap) near quantum phase transitions of the Ising universality class in one dimensional (1D) systems of finite size L. Prominent examp…
