Energy Levels of Quasiperiodic Hamiltonians , Spectral Unfolding , and Random Matrix
We consider a tight-binding Hamiltonian deened on the quasiperi-odic Ammann-Beenker tiling. Although the density of states (DOS) is rather spiky, the integrated DOS (IDOS) is quite smooth and can be used to perform spectral unfolding. The eeect of unfolding on the integrated level-spacing distribution is investigated for various parts of the spectrum which show diierent behaviour of the DOS. Fo...
متن کاملMobility Edge and Level Statistics of Random Tight-binding Hamiltonians
The energy level spacing distribution of a tight-binding hamiltonian is monitored across the mobility edge for a fixed disorder strength. Any mixing of extended and localized levels is avoided in the configurational averages, thus approaching the critical point very closely and with high energy resolution. By finite size scaling the method is shown to provide a very accurate estimate of the mob...
متن کاملQuantum Diffusion and Tunneling with Parametric Banded Random Matrix Hamiltonians
The microscopic origin of dissipation of a driven quantum many body system is addressed in the framework of a parametric banded random matrix approach. We find noticeable violations of the fluctuation–dissipation theorem and we observe also that the energy diffusion has a markedly non–Gaussian character. Within the Feynman–Vernon path integral formalism and in the Markovian limit, we further co...
متن کاملEnergy Levels of Quasiperiodic Hamiltonians, Spectral Unfolding, and Random Matrix Theory
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 (IDOS) is quite smooth and can be used to perform spectral unfolding. The effect of unfolding on the integrated level-spacing distribution is investigated for various parts of the spectrum which show different behaviour of the DOS. ...
متن کاملOptimal Non-Parametric Prediction Intervals for Order Statistics with Random Sample Size
In many experiments, such as biology and quality control problems, sample size cannot always be considered as a constant value. Therefore, the problem of predicting future data when the sample size is an integer-valued random variable can be an important issue. This paper describes the prediction problem of future order statistics based on upper and lower records. Two different cases for the ...
