A Note on the Analyticity of Density of States
Analyticity of Density of States Mathematical Physics
2012/5/9
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 emplo...
Uniform existence of the integrated density of states on metric Cayley graphs
random Schrodinger operator metric graph quantum graph integrated density of states
2011/7/27
Abstract: Given a finitely generated amenable group we consider ergodic random Schr\"odinger operators on a Cayley graph with random potentials and random boundary conditions. We show that the normali...
A Dispersion Relation for the Density of States With Application to the Casimir Effect
Dispersion Relation the Density of States the Casimir Effect

The trace of a function of a Schrodinger operator minus the same for the Laplacian can be expressed in terms of the determinant of its scattering matrix. The naive formula for this determinant is dive...

We propose a random matrix approach to describe vibrational excitations in disordered systems.
The dynamical matrix M is taken in the form M = AAT where A is some real (not generally
symmetric) rand...
Surface density of states and topological edge states in non-centrosymmetric superconductors
Surface density of states topological edge states non-centrosymmetric superconductors
2010/11/19
We study Andreev bound state (ABS) and surface density of state (SDOS) of non-centrosymmetric
superconductor where spin-singlet d-wave pairing mixes with spin-triplet p (or f)-wave one by spinorbit c...
Density of states of a graphene in the presence of strong point defects
graphene strong point defects
2010/11/19
The density of states near zero energy in a graphene due to strong point defects with random
positions are computed. Instead of focusing on density of states directly, we analyze eigenfunctions of in...
Computational Difficulty of Computing the Density of States
Computational Computing the Density of States
2010/11/5
We study the computational difficulty of computing the ground state degeneracy and the density of states for local Hamiltonians. We show that the difficulty of both problems is exactly captured by a c...
The Integrated Density of States for an Interacting Multiparticle Homogeneous Model and Applications to the Anderson Model
Multiparticle Homogeneous Model interacting quantum particles
2009/9/4
For a system of n interacting particles moving in the background of a “homogeneous” potential, we show that if the single particle Hamiltonian admits a density of states, so does the interacting n-par...

Liquid Water Sequential Monte Carlo/Quantum Mechanics Calculations DOS EG
2010/10/18
Electronic properties of liquid water were investigated by sequential Monte Carlo/Quantum mechanics calculations. The density of states (DOS) and HOMO-LUMO gap (EG) of liquid water have been determine...
