Examples of stationary BPS solutions in N=2 supergravity theories with R^2-interactions
G. L. Cardoso, B. de Wit, J. Käppeli +1
We discuss explicit examples of BPS solutions in four-dimensional N=2 supergravity with R^2-interactions. We demonstrate how to construct solutions by iteration. Generically, the p…
Bound States of D(2p)-D0 Systems and Supersymmetric p-Cycles
Ralph Blumenhagen, Volker Braun, Robert Helling
We discuss some issues related to D(2p)-D0 branes with background magnetic fluxes respectively, in a T-dual picture, Dp-Dp branes at angles. In particular, we describe the nature o…

We present non-supersymmetric toroidal compactifications of type I string theory with both constant background NSNS two-form flux and non-trivial magnetic flux on the various D9-br…
Four-Flux and Warped Heterotic M-Theory Compactifications
Gottfried Curio, Axel Krause
In the framework of heterotic M-theory compactified on a Calabi-Yau threefold 'times' an interval, the relation between geometry and four-flux is derived {\it beyond first order}.…
Dilaton Tadpoles, Warped Geometries and Large Extra Dimensions for Non-Supersymmetric Strings
Ralph Blumenhagen, Anamaria Font
We analyze the backreaction of dilaton tadpoles on the geometry of non-supersymmetric strings. After finding explicit warped solutions for a T-dual version of the Sugimoto model, w…
Novel Fine-Structure in the Low-Energy Excitation Spectrum of a High-Tc Superconductor by Polarization Dependent Photoemission

Angle-resolved photoemission spectroscopy is performed on single crystals of the single-layer high-Tc superconductor Bi(2)Sr(2-x)La(x)CuO(6+d) at optimal doping (x=0.4) in order to…
High-precision estimates of critical quantities by means of improved Hamiltonians
M. Campostrini, M. Hasenbusch, A. Pelissetto +2
Three-dimensional spin models of the Ising and XY universality classes are studied by a combination of high-temperature expansions and Monte Carlo simulations applied to improved H…
The Vacuum Polarization: Power Corrections beyond OPE ?
M. Gockeler, R. Horsley, W. Kurzinger +4
We compute the vacuum polarization on the lattice using non-perturbatively O(a) improved Wilson fermions. The result is compared with the operator product expansion (OPE).

We compute the 2n-point coupling constants in the high-temperature phase of the 2d Ising model by using transfer-matrix techniques. This provides the first few terms of the expansi…
Helicity modulus as renormalized coupling in the O(3) sigma-model

For the family of O(n) invariant nonlinear sigma-models we consider boundary conditions that are periodic up to an O(n) rotation. The helicity modulus is related to the change in f…
Ginsparg-Wilson Fermions in Odd Dimensions
W. Bietenholz, J. Nishimura
The Ginsparg-Wilson relation, if written in a suitable form, can be used as a condition for lattice Dirac operators of massless fermions also in odd dimensions. The fermion action…

M. Gockeler, R. Horsley, W. Kurzinger +5
Our previous calculation of the spin-dependent structure function g_2 is revisited. The interest in this structure function is to a great extent motivated by the fact that it recei…
