The Density of States and the Spectral Shift Density of Random Schroedinger Operators

open access: yes, 2000
In this article we continue our analysis of Schroedinger operators with a random potential using scattering theory. In particular the theory of Krein's spectral shift function leads to an alternative construction of the density of states in arbitrary ...

Density of States–Based Molecular Simulations

open access: yesAnnual Review of Chemical and Biomolecular Engineering, 2012
One of the central problems in statistical mechanics is that of finding the density of states of a system. Knowledge of the density of states of a system is equivalent to knowledge of its fundamental equation, from which all thermodynamic quantities can be obtained.

Quasiparticle spectrum of a type-II superconductor in a high magnetic field with randomly pinned vortices

open access: yes, 1999
We show that gapless superconductivity of a strongly type-II superconductor in a high magnetic field prevails in the presence of disorder, suggesting a topological nature.

COMPUTER SIMULATION OF THE ELECTRONIC STRUCTURE OF HEMATITE

open access: yesКонденсированные среды и межфазные границы, 2018
Abstarct. The results of ab initio computer modeling of the electronic structure of bulk rhomboedral hematite (α-Fe2O3) are presented. The spectra of total and local partial densities and bandstructures for both spin directions have been calculated using

The integrated density of states of the random graph Laplacian

open access: yes, 2010
We analyse the density of states of the random graph Laplacian in the percolating regime. A symmetry argument and knowledge of the density of states in the nonpercolating regime allows us to isolate the density of states of the percolating cluster (DSPC)

Collective single-photon emission and energy transfer in thin-layer dielectric and plasmonic systems

open access: yesNanophotonics
We study the collective photon decay of multiple quantum emitters embedded in a thin high-index dielectric layer such as hexagonal boron nitride (hBN), with and without a metal substrate.

A Note on the Analyticity of Density of States

open access: yes, 2012
We consider the $d$-dimensional Anderson model, and we prove the density of states is locally analytic if the single site potential distribution is locally analytic and the disorder is large. We employ the random walk expansion of resolvents and a simple

Density of states for random contractions [PDF]

open access: yesJournal of Spectral Theory, 2017
We define a linear functional, the DOS functional, on spaces of holomorphic functions on the unit disk which is associated with random ergodic contraction operators on a Hilbert space, in analogy with the density of states functional for random self-adjoint operators.

Tunneling Density of States of the Interacting Two-Dimensional Electron Gas

open access: yes, 2003
We investigate the influence of electron--electron interactions on the density of states of a ballistic two--dimensional electron gas. The density of states is determined nonperturbatively by means of path integral techniques allowing for reliable ...

Statistical density of nuclear excited states

open access: yesЯдерна фізика та енергетика, 2015
A semi-classical approximation is applied to the calculations of single-particle and statistical level densities in excited nuclei. Landau's conception of quasi-particles with the nucleon effective mass m* < m is used.
