A Dispersion Relation for the Density of States With Application to the Casimir Effect
Dispersion Relation the Density of States the Casimir Effect
2010/12/27
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...
On the high-density expansion for Euclidean Random Matrices
the high-density expansion Euclidean Random Matrices
2010/12/27
Diagrammatic techniques to compute perturbatively the spectral properties of Euclidean Random Matrices in the high-density regime are introduced and discussed in detail. Such techniques are developed ...
Density models for streamer discharges: beyond cylindrical symmetry and homogeneous media
cylindrical symmetry homogeneous media
2010/11/16
Streamer electrical discharges are often investigated with computer simulations of density models (also called drift-diffusion-reaction models). We review these models, detailing their physical found...
Source Mechanism of Long Period events recorded by a high density seismic network during the 2008 eruption on Mt Etna

2010/11/16
129 Long Period (LP) events, divided into two families of similar events, were recorded by the 50 stations deployed on Mount Etna in the second half of June 2008. During this period lava was flowing ...
We study various methods to generate ensembles of quantum density matrices of a fixed size N and analyze the corresponding probability distributions P(x), where x denotes the rescaled eigenvalue, x=N\...
