Relativistic Antihydrogen Production
Helmar Meier, Zlatko Halabuka, Kai Hencken +2
We calculate the production of relativistic antihydrogen atoms by bound-free pair production. The cross section is calculated in the semiclassical approximation (SCA), or equivalen…
Parametric resonance in atomic force microscopy: A new method to study the tip-surface interaction
Franz-Josef Elmer
We propose a new method to investigate interactions involved in atomic force microscopy (AFM). It is a dynamical method relying on the growth of oscillations via parametric resonan…
Controlling friction
Franz-Josef Elmer
Two different controlling methods are proposed to stabilize unstable continuous-sliding states of a dry-friction oscillator. Both methods are based on a delayed-feedback mechanism…
Front Propagation in Evanescent Media
M. Buttiker, H. Thomas
We investigate the time evolution of waves in evanescent media generated by a source within this medium and observed at some distance away from the location of the source. The aim…
The Galactic Bar
Ortwin Gerhard, James Binney, HongSheng Zhao
We summarize recent work on the structure and dynamics of the Galactic bar and inner disk. Current work focusses on constructing a quantitative model which integrates NIR photometr…
A standard stellar library for evolutionary synthesis: II. The M dwarf extension
T. Lejeune, F. Cuisinier, R. Buser
A standard library of theoretical stellar spectra intended for multiple synthetic photometry applications including spectral evolutionary synthesis is presented. The grid includes…
Self-Organized Criticality with Complex Scaling Exponents in the Train Model
Franz-Josef Elmer
The train model which is a variant of the Burridge-Knopoff earthquake model is investigated for a velocity-strengthening friction law. It shows self-organized criticality with comp…
Baker-Campbell-Hausdorff relation for special unitary groups SU(N)
Stefan Weigert
Multiplication of two elements of the special unitary group SU(N) determines uniquely a third group element. A BAker-Campbell-Hausdorff relation is derived which expresses the grou…
Macroscopic Quantum Tunneling of Ferromagnetic Domain Walls
Hans-Benjamin Braun, Jordan Kyriakidis, Daniel Loss
Quantum tunneling of domain walls out of an impurity potential in a mesoscopic ferromagnetic sample is investigated. Using improved expressions for the domain wall mass and for the…
Quantum Information is Physical
David P. DiVincenzo, Daniel Loss
We discuss a few current developments in the use of quantum mechanically coherent systems for information processing. In each of these developments, Rolf Landauer has played a cruc…
Type Ia Supernovae: Influence of the Initial Composition on the Nucleosynthesis, Light Curves, Spectra and Consequences for the Determination of Omega_M & Lambda
Peter Hoeflich, F. K. Thielemann, J. Craig Wheeler
The influence of the initial composition of the exploding white dwarf on the nucleosynthesis, light curves and spectra of Type Ia supernovae has been studied in order to evaluate t…
The Virgo cluster distance from 21 cm-line widths
M. Federspiel, G. A. Tammann, A. Sandage
The distance of the Virgo cluster is derived in the B band from the 21 cm-line width-absolute magnitude relation. The latter is calibrated using 18 spirals with Cepheid distances m…
Hard X- and Gamma-Rays from Type Ia Supernovae
Peter Hoeflich, J. Craig Wheeler, Alexei Khokhlov
The gamma-ray light curves and spectra are presented for a set of theoretical Type Ia supernova models including deflagration, detonation, delayed detonation, and pulsating delayed…
The distribution of nearby stars in phase space mapped by Hipparcos: I. The potential well and local dynamical mass
M. Crézé, E. Chereul, O. Bienaymé +1
Hipparcos data provide the first, volume limited and absolute magnitude limited homogeneous tracer of stellar density and velocity distributions in the solar neighbourhood. The den…
The Casson-Walker-Lescop Invariant as a Quantum 3-manifold Invariant
Nathan Habegger, Anna Beliakova
We give a direct computational proof that the degree 1 part of the Le-Murakami-Ohtsuki invariant of a closed oriented 3-manifold M is determined by the Casson-Walker-Lescop invaria…
Macroscopic Quantum Coherence in Molecular Magnets
Alain Chiolero, Daniel Loss
We study macroscopic quantum coherence in antiferromagnetic molecular magnets in the presence of magnetic fields. Such fields generate artificial tunnel barriers with externally tu…
Velocity structure of the dwarf galaxy population in the Centaurus cluster
P. Stein, H. Jerjen, M. Federspiel
Based on the photometric survey of the inner region of the Centaurus cluster (Jerjen & Dressler 1997a) we measured redshifts for a deep, surface brightness limited sample of galaxi…
Bremsstrahlung Pair Production In Relativistic Heavy Ion Collision
H. Meier, K. Hencken, D. Trautmann +1
We calculate production of electron- and muon-pairs by the bremsstrahlung process in hadron collisions and compare it with the dominant two-photon process. Results for the total cr…
Nonlinear Dynamics of Dry Friction
Franz-Josef Elmer
The dynamical behavior caused by dry friction is studied for a spring-block system pulled with constant velocity over a surface. The dynamical consequences of a general type of phe…
Nuclear Level Density and the Determination of Thermonuclear Rates for Astrophysics
T. Rauscher, F. -K. Thielemann, K. -L. Kratz
The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. We discuss the model mostly employed for such calculations: the stati…
An HI line search for optically identified dwarf galaxy candidates in the M81 group
W. van Driel, R. C. Kraan-Korteweg, B. Binggeli +1
Sensitive 21cm HI line observations were performed for 23 dwarf members and possible members of the nearby M81 group of galaxies, including five objects of a clustering of extremel…
Nucleosynthesis in Type Ia Supernovae
K. Nomoto, K. Iwamoto, N. Nakasato +5
Among the major uncertainties involved in the Chandrasekhar mass models for Type Ia supernovae are the companion star of the accreting white dwarf (or the accretion rate that deter…
Nucleosynthesis in Type II Supernovae
K. Nomoto, M. Hashimoto, T. Tsujimoto +3
Presupernova evolution and explosive nucleosynthesis in massive stars for main-sequence masses from 13 to 70 are calculated. We examine the dependence of the su…
Comment on the dispersion-velocity of galactic dark matter particles
O. Bienaymé, C. Pichon
In a recent Letter, Cowsik, Ratnam and Bhattacharjee (1996a) have built a dynamically self-consistent spatial distribution of particles of galactic dark matter. They have come up w…
