Estimating Vaccine Coverage by Using Computer Algebra
D. Altmann, K. Altmann
The approach of N. Gay for estimating the coverage of a multivalent vaccine from antibody prevalence data in certain age cohorts is improved by using computer aided elimination the…
Orbifolds of AdS(3) and fixpoints of the CFT
Klaus Behrndt
The 3-d BTZ black hole represents an orbifold of gravity. The UV as well as the IR region of the CFT is governed by a gauged SL(2, R) WZW model. In the UV it corresponds to…
Measurement of D* Meson Cross Sections at HERA and Determination of the Gluon Density in the Proton using NLO QCD
C. Adloff
With the H1 detector at the ep collider HERA, D* meson production cross sections have been measured in deep inelastic scattering with four-momentum transfers Q^2>2 GeV2 and in phot…
Gauged O(n) spin models in one dimension
M. Hasenbusch, R. R. Horgan
We consider a gauged O(n) spin model, n >= 2, in one dimension which contains both the pure O(n) and RP(n-1) models and which interpolates between them. We show that this model is…
Conformal Field Theory in Conformal Space
C. R. Preitschopf, M. A. Vasiliev
We present a new framework for a Lagrangian description of conformal field theories in various dimensions based on a local version of d+2-dimensional conformal space. The results i…
Confining Properties of Abelian(-Projected) Theories
Dmitri Antonov, Dietmar Ebert
Representations of the Abelian-projected SU(2)- and SU(3)-gluodynamics in terms of the magnetic monopole currents are derived. Besides the quadratic part, the obtained effective ac…
A comparison of the eigenvalues of the Dirac and Laplace operator on the two-dimensional torus
Ilka Agricola, Bernd Ammann, Thomas Friedrich
We compare the eigenvalues of the Dirac and Laplace operator on a two-dimensional torus with respect to the trivial spin structure. In particular, we compute their variation up to…
Ferromagnetism and the temperature-dependent electronic structure in thin Hubbard films
T. Herrmann, W. Nolting
The magnetic behavior of thin ferromagnetic itinerant-electron films is investigated within the strongly correlated single-band Hubbard model. For its approximate solution we apply…
Non-Extreme Black Holes of Five Dimensional N=2 AdS Supergravity
K. Behrndt, M. Cvetic, W. A. Sabra
We derive and analyse the full set of equations of motion for non-extreme static black holes (including examples with the spatial curvatures k=-1 and k=0) in D=5 N=2 gauged supergr…
Dissipative properties of vibrated granular materials
Clara Saluena, Thorsten Poeschel, Sergei E. Esipov
We investigate collective dissipative properties of vibrated granular materials by means of molecular dynamics simulations. Rates of energy losses indicate three different regimes…
Background Configurations, Confinement and Deconfinement on a Lattice with BPS Monopole Boundary Conditions
E. -M. Ilgenfritz, S. V. Molodtsov, M. Müller-Preussker +1
Finite temperature SU(2) lattice gauge theory is investigated in a 3D cubic box with fixed boundary conditions provided by a discretized, static BPS monopole solution with varying…
N=1 Supersymmetric Gauge Theories and Supersymmetric 3-cycles
Andreas Karch, Dieter Lust, Andre Miemiec
In this paper we discuss the strong coupling limit of chiral N=1 supersymmetric gauge theory via their embedding into M-theory. In particular we focus on the brane box models of Ha…
The velocities of light in modified QED vacua
K. Scharnhorst
QED vacua under the influence of external conditions (background fields, finite temperature, boundary conditions) can be considered as dispersive media whose complex behaviour can…

A. Kharchilava, T. Lohse, A. Somov +1
The production of mesons in fixed target collisions is considered. It is shown that Non-Relativistic QCD predicts states to be produced with sizeable transverse polari…

The correlation-driven transition from a paramagnetic metal to a paramagnetic Mott-Hubbard insulator is studied within the half-filled Hubbard model for a thin-film geometry. We co…

Using the dynamical mean-field theory, we calculate the effective electron mass in the Hubbard model on a semi-infinite lattice. At the surface the effective mass is strongly enhan…
