Type IIB Theory on Half-flat Manifolds
Sebastien Gurrieri, Andrei Micu
In this note we derive the low-energy effective action of type IIB theory compactified on half-flat manifolds and we show that this precisely coincides with the low-energy effectiv…
Intersecting D5-brane models with massive vector-like leptons
D. Bailin, G. V. Kraniotis, A. Love
We construct eight-stack intersecting D5-brane models, with an orbifold transverse space, that yield the (non-supersymmetric) standard model up to vector-like leptons. The matter i…
Four-point functions in N=4 SYM
P. J. Heslop, P. S. Howe
A new derivation is given of four-point functions of charge chiral primary multiplets in N=4 supersymmetric Yang-Mills theory. A compact formula, valid for arbitrary , is gi…
Mirror Symmetry in Generalized Calabi-Yau Compactifications
Sebastien Gurrieri, Jan Louis, Andrei Micu +1
We discuss mirror symmetry in generalized Calabi-Yau compactifications of type II string theories with background NS fluxes. Starting from type IIB compactified on Calabi-Yau three…
Localization of a Gaussian polymer in a weak periodic surface potential disturbed by a single defect
Andrei A. Fedorenko, Semjon Stepanow
Using the results of the recently studied problem of adsorption of a Gaussian polymer in a weak periodic surface potential we study the influence of a single rod like defect on the…
Discrete Riccati equation, hypergeometric functions and circle patterns of Schramm type
S. I. Agafonov
Square grid circle patterns with prescribed intersection angles, mimicking holomorphic maps z^a and log(z) are studied. It is shown that the corresponding circle patterns are imbed…
Polarized x-ray absorption spectra of CuGeO3 at the Cu and Ge K edges
Ondrej Sipr, Antonin Simunek, Sergey Bocharov +1
Polarized x-ray absorption near edge structure (XANES) spectra at both the Cu and the Ge K-edges of CuGeO3 are measured and calculated relying on the real-space multiple-scattering…
Standard-like models from Intersecting D5-branes
D. Bailin, G. V. Kraniotis, A. Love
We construct intersecting D5-brane orbifold models that yield the (non-supersymmetric) standard model up to vector-like matter and charged-singlet scalars. The models are constrain…
Depinning transition at the upper critical dimension
Andrei A. Fedorenko, Semjon Stepanow
We study the effect of quenched random field disorder on a driven elastic interface close to the depinning transition at the upper critical dimension d_{c}=4 using the functional r…
New Standard-like Models from Intersecting D4-Branes
D. Bailin, G. V. Kraniotis, A. Love
We construct a new set of intersecting D4-brane models that yield the (non-supersymmetric) standard model up to vector-like matter and, in some cases, extra U(1) factors in the gau…
The distribution function of a semiflexible polymer and random walks with constraints
Semjon Stepanow, Gunter M. Schuetz
In studying the end-to-end distribution function of a worm like chain by using the propagator method we have established that the combinatorial problem of counting the pat…
M5-branes with 3/8 supersymmetry in pp-wave background
Harvendra Singh
We construct M5-branes in pp-wave background and find that they preserve exactly half of the background pp-wave supersymmetries. We explicitly write down the standard as well as su…
Slater-Pauling Behavior of the Half-Ferromagnetic Full-Heusler Alloys
I. Galanakis, P. H. Dederichs, N. Papanikolaou
Using the full-potential screened Korringa-Kohn-Rostoker method we study the full-Heusler alloys based on Co, Fe, Rh and Ru. We show that many of these compounds show a half-metall…
Supersymmetry Breaking and alpha'-Corrections to Flux Induced Potentials
Katrin Becker, Melanie Becker, Michael Haack +1
We obtain the vacuum solutions for M-theory compactified on eight-manifolds with non-vanishing four-form flux by analyzing the scalar potential appearing in the three-dimensional t…
Orbifolds and Flows from Gauged Supergravity
Richard Corrado, Murat Gunaydin, Nicholas P. Warner +1
We examine orbifolds of the IIB string via gauged supergravity. For the gravity duals of the A_{n-1} quiver gauge theories, we extract the massless degrees of freedom and assemble…
Origin and Properties of the Gap in the Half-Ferromagnetic Heusler Alloys
I. Galanakis, P. H. Dederichs, N. Papanikolaou
We study the origin of the gap and the role of chemical composition in the half-ferromagnetic Heusler alloys using the full-potential screened KKR method. In the paramagnetic phase…
Type II Theories Compactified on Calabi-Yau Threefolds in the Presence of Background Fluxes
Jan Louis, Andrei Micu
Compactifications of type II theories on Calabi-Yau threefolds including electric and magnetic background fluxes are discussed. We derive the bosonic part of the four-dimensional l…
Romans type IIA theory and the heterotic strings
Harvendra Singh
In this paper we study compactification of 6-dimensional massive type IIA supergravity in presence of Ramond-Ramond background fluxes. The resulting theory in four dimensions…
