Dynamical Scaling Properties of Electrons in Quantum Systems with Multifractal Eigenstates
Jianxin Zhong, Zhenyu Zhang, Michael Schreiber +2
We study the intricate relationships between the dynamical scaling properties of electron wave packets and the multifractality of the eigenstates in quantum systems. Numerical simu…

Energy Levels of Quasiperiodic Hamiltonians, Spectral Unfolding, and Random Matrix Theory
Michael Schreiber, Uwe Grimm, Rudolf A. Roemer +1
We consider a tight-binding Hamiltonian defined on the quasiperiodic Ammann-Beenker tiling. Although the density of states (DOS) is rather spiky, the integrated DOS is quite smooth…
