Magnetic layers with periodic point perturbations
P. Exner, K. Nemcova
We study spectral properties of a spinless quantum particle confined to an infinite planar layer with hard walls which interacts with a periodic lattice of point perturbations and…
Critical region for droplet formation in the two-dimensional Ising model
Marek Biskup, Lincoln Chayes, Roman Kotecky
We study the formation/dissolution of equilibrium droplets in finite systems at parameters corresponding to phase coexistence. Specifically, we consider the 2D Ising model in volum…
Microscopic foundations of nuclear supersymmetry
Hendrik B Geyer, Pavel Cejnar
We discuss a microscopic framework for phenomenological boson-fermion models of nuclear structure based on the U() type of superalgebras. The generalized Dyson mapping of ferm…
Gamma photometric redshifts for long gamma-ray bursts
Z. Bagoly, I. Csabai, A. Mészáros +4
It is known that the soft tail of the gamma-ray bursts' spectra show excesses from the exact power-law dependence. In this article we show that this departure can be detected in th…
Bose-Einstein Correlations of Charged Kaons in Central Pb+Pb Collisions at
S. V. Afanasiev
Bose-Einstein correlations of charged kaons were measured near mid-rapidity in central Pb+Pb collisions at 158 AGeV by the NA49 experiment at the CERN SPS. Source radii were…
Geodesics in spacetimes with expanding impulsive gravitational waves
Jiri Podolsky, Roland Steinbauer
We study geodesic motion in expanding spherical impulsive gravitational waves propagating in a Minkowski background. Employing the continuous form of the metric we find and examine…
Impulsive waves in electrovac direct product spacetimes with Lambda
Marcello Ortaggio, Jiri Podolsky
A complete family of non-expanding impulsive waves in spacetimes which are the direct product of two 2-spaces of constant curvature is presented. In addition to previously investig…
Energy Dependence of and Production at CERN-SPS Energies
A. Mischke
Rapidity distributions for and hyperons in central Pb-Pb collisions at 40, 80 and 158 AGeV and for mesons at 158 AGeV are presented. The…
A 3+1 covariant suite of Numerical Relativity Evolution Systems
C. Bona, T. Ledvinka, C. Palenzuela
A suite of three evolution systems is presented in the framework of the 3+1 formalism. The first one is of second order in space derivatives and has the same causal structure of th…
The Locally Fine Coreflection and Normal Covers in the Products of Partition-complete Spaces
Aarno Hohti, Miroslav Husek, Jan Pelant
We prove that the countable product of supercomplete spaces having a countable closed cover consisting of partition-complete subspaces is supercomplete with respect to its metric-f…
An interpretation of Robinson-Trautman type N solutions
J. B. Griffiths, J. Podolsky, P. Docherty
The Robinson-Trautman type N solutions, which describe expanding gravitational waves, are investigated for all possible values of the cosmological constant Lambda and the curvature…
Recent results on spectra and yields from NA49
M. van Leeuwen
The energy dependence of hadron production in central Pb+Pb collisions is presented and discussed. In particular, midrapidity -spectra for , , , , ,…
Selective advantage of topological disorder in biological evolution
Michal Kolář, František Slanina
We examine a model of biological evolution of Eigen's quasispecies in a holey fitness landscape, where the fitness of a site is either 0 (lethal site) or a uniform positive constan…
Search for the Production of Single Sleptons through R-parity Violation in p bar{p} Collisions at sqrt{s}=1.8 TeV
D0 collaboration, V. M. Abazov
We report the first search for supersymmetric particles via s-channel production and decay of smuons or muon sneutrinos at hadronic colliders. The data for the two-muon and two-jet…
Detection of the BL Lac object 1ES1426+428 in the Very High Energy gamma-ray band by the CAT Telescope from 1998-2000
A. Djannati-Atai, B. Khelifi, S. Vorobiov +14
The BL Lac Object 1ES 1426+428, at a red-shift of z=0.129, has been monitored by the CAT telescope from February 1998 to June 2000. The accumulation of 26 hours of observations sho…
On the Reality of the Accelerating Universe
Attila Meszaros
Two groups recently deduced the positive value for the cosmological constant, concluding at a high (>= 99%) confidence level that the Universe should be accelerating. This conclusi…
An ADAF in the Kerr metric: propagation of a wave pattern
T. Musil, V. Karas
Time evolution of an advection-dominated accretion flow is explored in terms of relativistic fluid equations. An axially symmetric, vertically averaged mean flow is constructed and…
Search for Excited Electrons at HERA
H1 Collaboration, C. Adloff
A search for excited electron e* production is described in which the electroweak decays e*->e gamma, e*->e Z and e*->nu W are considered. The data used correspond to an integrated…
On the formation/dissolution of equilibrium droplets
Marek Biskup, Lincoln Chayes, Roman Kotecky
We consider liquid-vapor systems in finite volume at parameter values corresponding to phase coexistence and study droplet formation due to a fixed excess of pa…
