Note on the set of Bragg peaks with high intensity
Daniel Lenz, Nicolae Strungaru
We consider diffraction of Delone sets in Euclidean space. We show that the set of Bragg peaks with high intensity is always Meyer (if it is relatively dense). We use this to provi…
Hyperbolicity of High Order Systems of Evolution Equations
David Hilditch, Ronny Richter
We study properties of evolution equations which are first order in time and arbitrary order in space (FTNS). Following Gundlach and Martín-García (2006) we define strong and symme…
Observation of bound states in Lieb photonic lattices
Rodrigo A. Vicencio, Camilo Cantillano, Luis Morales-Inostroza +4
We present the first experimental demonstration of a new type of bound states in the continuum, namely, compacton-like linear states in flat bands lattices. To this end, photonic L…
Relativistic calculations of double -shell photoionization for neutral medium- atoms
V. A. Yerokhin, A. Surzhykov, S. Fritzsche
Fully relativistic calculations are presented for the double -shell photoionization cross section for several neutral medium- atoms, from magnesium () up to silver ($…
ALMA observations of alpha Centauri: First detection of main-sequence stars at 3mm wavelength
R. Liseau, W. Vlemmings, A. Bayo +19
The precise mechanisms that provide the non-radiative energy for heating the chromosphere and the corona of the Sun and those of other stars constitute an active field of research.…
Stepwise contraction of the nf Rydberg shells in the 3d photoionization of multiply-charged xenon ions
S. Schippers, A. Borovik, T. Buhr +8
Triple photoionization of Xe3+, Xe4+ and Xe5+ ions has been studied in the energy range 670-750 eV, including the 3d ionization threshold. The photon-ion merged-beam technique was…
