The Geometric Thickness of Low Degree Graphs

Christian A. Duncan, David Eppstein, Stephen G. Kobourov

We prove that the geometric thickness of graphs whose maximum degree is no more than four is two. All of our algorithms run in O(n) time, where n is the number of vertices in the g…

Using Atomic Diffraction of Na from Material Gratings to Measure Atom-Surface Interactions

John D. Perreault, Alexander D. Cronin, T. A. Savas

In atom optics a material structure is commonly regarded as an amplitude mask for atom waves. However, atomic diffraction patterns formed using material gratings indicate that mate…

Quantum signatures of breather-breather interactions

J. Dorignac, J. C. Eilbeck, M. Salerno +1

The spectrum of the Quantum Discrete Nonlinear Schrödinger equation on a periodic 1D lattice shows some interesting detailed band structure which may be interpreted as the quantum…

The data analysis of HD209458 Ly-alpha transit occultation

J. -M. Désert, A. Vidal-Madjar, A. Lecavelier des Étangs +4

Using STIS - HST observations, we have detected an extended upper atmosphere in the extrasolar planet HD209458b . The spectra show an absorption of (15+/-4)% of the stellar Ly-alph…

Jahn-Teller Distortions and the Supershell Effect in Metal Nanowires

D. F. Urban, J. Bürki, C. -H. Zhang +2

A stability analysis of metal nanowires shows that a Jahn-Teller deformation breaking cylindrical symmetry can be energetically favorable, leading to stable nanowires with elliptic…

Evolution of the polarization of the optical afterglow of the gamma-ray burst GRB 030329

J. Greiner, S. Klose, K. Reinsch +23

We report 31 polarimetric observations of the afterglow of GRB 030329 with high signal-to-noise and high sampling frequency. We establish the polarization light curve, detect susta…
