Heterotic Vacua from general (non-) Abelian Bundles
Timo Weigand
We report on the construction of four-dimensional string vacua by considering general abelian and non-abelian bundles on an internal Calabi-Yau for both heterotic theories. The str…
Standard Model statistics of a Type II orientifold
Florian Gmeiner
We analyse four-dimensional, supersymmetric intersecting D-brane models in a toroidal orientifold background from a statistical perspective. The distribution and correlation of obs…
3D-Hydrogen Analysis of Ferromagnetic Microstructures in Proton Irradiated Graphite
P. Reichart, D. Spemann, A. Hauptner +9
Recently, magnetic order in highly oriented pyrolytic graphite (HOPG) induced by proton broad- and microbeam irradiation was discovered. Theoretical models propose that hydrogen co…
Interpreting the Hydrogen IR Lines - Impact of Improved Electron Collision Data
Norbert Przybilla, Keith Butler
We evaluate the effect of variations in the electron-impact excitation cross sections on the non-LTE line formation for hydrogen in early-type stars. While the Balmer lines are bas…
Probing for evolutionary links between local ULIRGs and QSOs from NIR spectroscopy
K. M. Dasyra, L. J. Tacconi, R. I. Davies +6
We present a study of the dynamical evolution of Ultraluminous Infrared Galaxies (ULIRGs), merging galaxies of infrared luminosity >10^12 L_sun. During our Very Large Telescope lar…
Relativity and Lorentz Invariance of Entanglement Distillability
L. Lamata, M. A. Martin-Delgado, E. Solano
We study entanglement distillability of bipartite mixed spin states under Wigner rotations induced by Lorentz transformations. We define weak and strong criteria for relativistic i…
Phase Transitions and Spatio-Temporal Fluctuations in Stochastic Lattice Lotka-Volterra Models
Mauro Mobilia, Ivan T. Georgiev, Uwe C. Tauber
We study the general properties of stochastic two-species models for predator-prey competition and coexistence with Lotka-Volterra type interactions defined on a -dimensional la…
Quantum diffusion of the random Schrodinger evolution in the scaling limit
Laszlo Erdos, Manfred Salmhofer, Horng-Tzer Yau
We consider random Schrödinger equations on $\bR^d$ for with a homogeneous Anderson-Poisson type random potential. Denote by the coupling constant and the soluti…
On the conformal systoles of four-manifolds
M. J. D. Hamilton
We extend a result of M. Katz on conformal systoles to all four-manifolds with b^+=1 which have odd intersection form. The same result holds for all four-manifolds with b^+=1 with…
Classification of Supersymmetric Flux Vacua in M Theory
Klaus Behrndt, Mirjam Cvetic, Tao Liu
We present a comprehensive classification of supersymmetric vacua of M-theory compactification on seven-dimensional manifolds with general four-form fluxes. We analyze the cases wh…
Probing the topological structure of the QCD vacuum with overlap fermions
E. -M. Ilgenfritz, K. Koller, Y. Koma +3
Overlap fermions implement exact chiral symmetry on the lattice and are thus an appropriate tool for investigating the chiral and topological structure of the QCD vacuum. We study…
The Role of Architecture in the Elastic Response of Semiflexible Polymer and Fiber Networks
Claus Heussinger, Erwin Frey
We study the elasticity of cross-linked networks of thermally fluctuating stiff polymers. As compared to their purely mechanical counterparts, it is shown that these thermal networ…
From Intracellular Traffic to a Novel Class of Driven Lattice Gas Models
Hauke Hinsch, Roger Kouyos, Erwin Frey
Motor proteins are key players in intracellular transport processes and biological motion. Theoretical modeling of these systems has been achieved by the use of step processes on o…
Formation of early-type galaxies from cosmological initial conditions
Thorsten Naab, Peter H. Johansson, Jeremiah P. Ostriker +1
We describe high resolution Smoothed Particle Hydrodynamics (SPH) simulations of three approximately field galaxies starting from \LCDM initial conditions. The simulations ar…
Enhancing the tensor-to-scalar ratio in simple inflation
V. Mukhanov, A. Vikman
We show that in theories with a nontrivial kinetic term the contribution of the gravitational waves to the CMB fluctuations can be substantially larger than that is naively expecte…
Canonical p-dimensions of algebraic groups and degrees of basic polynomial invariants
Kirill Zainoulline
In the present notes we provide a new uniform way to compute a canonical p-dimension of a split algebraic group G for a torsion prime p using degrees of basic polynomial invariants…
Measurement of the Isolated Photon Cross Section in p-pbar Collisions at sqrt{s}=1.96 TeV
D0 Collaboration
The cross section for the inclusive production of isolated photons has been measured in p anti-p collisions at sqrt{s}=1.96 TeV with the D0 detector at the Fermilab Tevatron Collid…
Truly On-The-Fly LTL Model Checking
Moritz Hammer, Alexander Knapp, Stephan Merz
We propose a novel algorithm for automata-based LTL model checking that interleaves the construction of the generalized Büchi automaton for the negation of the formula and the empt…
Gluon polarization in the nucleon from quasi-real photoproduction of high-pT hadron pairs
COMPASS Collaboration, E. S. Ageev
We present a determination of the gluon polarization Delta G/G in the nucleon, based on the helicity asymmetry of quasi-real photoproduction events, Q^2<1(GeV/c)^2, with a pair of…
Noncommutative Geometry and Gravity
Paolo Aschieri, Marija Dimitrijevic, Frank Meyer +1
We study a deformation of infinitesimal diffeomorphisms of a smooth manifold. The deformation is based on a general twist. This leads to a differential geometry on a noncommutative…
Analysis of a single-atom dipole trap
Markus Weber, Juergen Volz, Karen Saucke +2
We describe a simple experimental technique which allows to store a single Rubidium 87 atom in an optical dipole trap. Due to light-induced two-body collisions during the loading s…
Modelization of the EOS
C. Fuchs, H. H. Wolter
This article summarizes theoretical predictions for the density and isospin dependence of the nuclear mean field and the corresponding nuclear equation of state. We compare predict…
Stability of atoms in the Brown-Ravenhall model
Sergey Morozov, Semjon Vugalter
We consider the Brown--Ravenhall model of a relativistic atom with N electrons and a nucleus of charge Z and prove the existence of an infinite number of discrete eigenvalues for N…
The process of most recent common ancestors in an evolving coalescent
P. Pfaffelhuber, A. Wakolbinger
Consider a haploid population which has evolved through an exchangeable reproduction dynamics, and in which all individuals alive at time have a most recent common ancestor (MR…
