Moduli Stabilization and Inflationary Cosmology with Poly-Instantons in Type IIB Orientifolds
Ralph Blumenhagen, Xin Gao, Thorsten Rahn +1
Equipped with concrete examples of Type IIB orientifolds featuring poly-instanton corrections to the superpotential, the effects on moduli stabilization and inflationary cosmology…
A Note on Poly-Instanton Effects in Type IIB Orientifolds on Calabi-Yau Threefolds
Ralph Blumenhagen, Xin Gao, Thorsten Rahn +1
The zero mode structure for the generation of poly-instanton corrections for Euclidian D3-branes wrapping complex surfaces in Type IIB orientifolds with O7- and O3-planes is analyz…
Target Space Dualities of Heterotic Grand Unified Theories
Thorsten Rahn
In this article we summarize and extend the ideas and investigations on so called target space dualities of heterotic models with (0,2) worldsheet supersymmetry as they were partly…
Landscape Study of Target Space Duality of (0,2) Heterotic String Models
Ralph Blumenhagen, Thorsten Rahn
In the framework of (0,2) gauged linear sigma models, we systematically generate sets of perturbatively dual heterotic string compactifications. This target space duality is first…
Computational Tools for Cohomology of Toric Varieties
Ralph Blumenhagen, Benjamin Jurke, Thorsten Rahn
In this review, novel non-standard techniques for the computation of cohomology classes on toric varieties are summarized. After an introduction of the basic definitions and proper…
Cohomology of Line Bundles: Applications
Ralph Blumenhagen, Benjamin Jurke, Thorsten Rahn +1
Massless modes of both heterotic and Type II string compactifications on compact manifolds are determined by vector bundle valued cohomology classes. Various applications of our re…
