The Premartensite and Martensite in Fe50Rh50 System
Esmaeil Adabifiroozjaei, Fernando Maccari, Lukas Schaefer +19
Metallic/intermetalic materials with BCC structures hold an intrinsic instability due to phonon softening along [110] dirrection, causing BCC to lower-symmetry phases transformatio…
Influence of electron cooling on the polarization lifetime of a horizontally polarized storage ring beam
S. Karanth, E. Stephenson, A. Wronska +26
A previous publication has shown that the in-plane polarization (IPP) component of a polarized 0.97-GeV/c deuteron beam in the COSY storage ring may acquire a polarization half-lif…
Characterization of the JUDIDT Readout Electronics for Neutron Detection
R. Fabbri, U. Clemens, R. Engels +3
The Group for the development of neutron and gamma detectors in the Central Institute of Engineering, Electronics and Analytics (ZEA-2) at Forschungszentrum Juelich (FZJ) has devel…
A Data Acquisition and Monitoring System for the Detector Development Group at FZJ/ZEA-2
Riccardo Fabbri, Forschungszentrum Juelich
The central institute of electronics (ZEA-2) in the Forschungszentrum Juelich (FZJ) has developed the novel readout electronics JUDIDT to cope with high-rate data acquisition of th…
Electron and Photon Scattering on Three-Nucleon Bound States
J. Golak, R. Skibinski, H. Witala +3
A big spectrum of processes induced by real and virtual photons on the 3He and 3H nuclei is theoretically investigated through many examples based on nonrelativistic Faddeev calcul…
Ultraperipheral Collisions
Kai Hencken, Gerhard Baur, Ute Dreyer +1
Ultraperipheral collisions at heavy ion colliders use the strong Coulomb fields surrounding the ions to study photon-photon and photon-hadron processes at high energy. A number of…
Theoretical current-voltage characteristics of ferroelectric tunnel junctions
H. Kohlstedt, N. A. Pertsev, J. Rodriguez Contreras +1
We present the concept of ferroelectric tunnel junctions (FTJs). These junctions consist of two metal electrodes separated by a nanometer-thick ferroelectric barrier. The current-v…
Polarization states of polydomain epitaxial Pb(Zr1-xTix)O3 thin films and their dielectric properties
V. G. Kukhar, N. A. Pertsev, H. Kohlstedt +1
Ferroelectric and dielectric properties of polydomain (twinned) single-crystal Pb(Zr1-xTix)O3 thin films are described with the aid of a nonlinear thermodynamic theory, which has b…
Exchange parameters in Fe-based molecular magnets
A. V. Postnikov, G. Bihlmayer, S. Bluegel
The calculation of interatomic magnetic exchange interactions entering the Heisenberg model from the standpoint of the density functional theory (DFT) is outlined for two Fe-based…
Shot noise of large charge quanta in superconductor/semiconductor/superconductor junctions
F. E. Camino, V. V. Kuznetsov, E. E. Mendez +3
We have found experimentally that the noise of ballistic electron transport in a superconductor/semiconductor/superconductor junction is enhanced relative to the value given by the…
Andreev reflection and enhanced subgap conductance in NbN/Au/InGaAs-InP junctions
I. E. Batov, Th. Schaepers, A. A. Golubov +1
We report on the fabrication of highly transparent superconductor/normal metal/two-dimensional electron gas junctions formed by a superconducting NbN electrode, a thin (10nm) Au in…
Electron Spectroscopy and Density-Functional Study of "Ferric Wheel" Molecules
A. V. Postnikov, S. G. Chiuzbaian, M. Neumann +1
The Li-centered "ferric wheel" molecules with six oxo-bridged iron atoms form molecular crystals. We probed their electronic structure by X-ray photoelectron (XPS) and soft X-ray e…
Bicontinuous surfaces in self-assembling amphiphilic systems
U. S. Schwarz, G. Gompper
Amphiphiles are molecules which have both hydrophilic and hydrophobic parts. In water- and/or oil-like solvent, they self-assemble into extended sheet-like structures due to the hy…
Diffractive Vector Meson Production in k_t-Factorization Approach
I. P. Ivanov, N. N. Nikolaev
We describe the current status of the diffractive vector meson production calculations within the k_t-factorization approach. Since the amplitude of the vector meson production off…
The lifetime of the Lambda hyperon bound in hypernuclei produced by p+U collisions
P. Kulessa, W. Cassing, L. Jarczyk +5
The nonmesonic decay of the Lambda hyperon has been investigated by observation of delayed fission from heavy hypernuclei produced in proton-U collisions at Tp = 1.9 GeV. The lifet…
Bending Frustration of Lipid-Water Mesophases Based on Cubic Minimal Surfaces
U. S. Schwarz, G. Gompper
Inverse bicontinuous cubic phases are ubiquitous in lipid-water mixtures and consist of a lipid bilayer forming a cubic minimal surface, thereby dividing space into two cubic netwo…
Lattice Gauge Theory - A short Primer
G. Münster, M. Walzl
In this contribution we give an introduction to the foundations and methods of lattice gauge theory. Starting with a brief discussion of the quantum mechanical path integral, we de…
Hybrid Baryons, a brief review
T. Barnes
This contribution is a brief review of the status of hybrid baryons, which are hypothetical baryons that incorporate a gluonic excitation. We first summarize the status of hybrid m…
MESON2000 Conference Summary
