Aspects of String Compactification
… addresses some interesting problems in string compactification relevant to phenomenology, especially cosmological models derived from string theory Most attention is drawn to stabilizing the moduli and discussing the cosmology solutions given the effective potential obtained from string …

Extending the Geometric Tools of Heterotic String Compactification and Dualities
… the apparent relationship between two heterotic compactifications seen in (0,2) heterotic target space dual pairs should, in principle, induce some putative correspondence between the dual F-theory geometries. It has previously been conjectured in the literature that (0,2) target space duality …

Spectral and Superpotential Effects in Heterotic Compactifications
… related to the geometry and physics of heterotic string compactification. After an introduction to some of the basic ideas of this field, we review the heterotic line bundle standard model construction and a complex structure mod- uli stabilization mechanism associated to certain hidden sector …

Gauge symmetries and charged matter in F-theory
F-theory has emerged as a powerful tool for string compactification, as it can realize a number of string vacua with varying gauge groups, charged matter, and other properties. However, some aspects of F-theory are still not completely understood, particularly those involving charged matter. There …

Aspects of Supersymmetry
This thesis is devoted to a discussion of various aspects of supersymmetric quantum field theories in four and two dimensions. In four dimensions, 𝒩 = 1 supersymmetric quantum gauge theories on various four-manifolds are constructed. Many of their properties, some of which are distinct to the …

Notes on Some (0,2) Supersymmetric Theories in Two Dimensions
This thesis is devoted to a discussion of two-dimensional theories with (0,2) supersymmetry. Examples of two-dimensional (0,2) gauged linear sigma models (GLSMs) are constructed for various spaces including Grassmannians, complete intersections in Grassmannians, and non-complete intersections such …

Applications of Numerical Methods in Heterotic Calabi-Yau Compactification
… different problems in heterotic Calabi-Yau compactification. We review algorithms for computing both the Ricci-flat metric on Calabi-Yau manifolds and Hermitian Yang-Mills connections on poly-stable holomorphic vector bundles over those spaces. We apply the numerical techniques for obtaining …
