Large field ranges from aligned and misaligned winding

Journal of High Energy Physics, 2019
We search for effective axions with super-Planckian decay constants in type IIB string models. We argue that such axions can be realised as long winding trajectories in complex-structure moduli space by an appropriate flux choice.

When rational sections become cyclic — Gauge enhancement in F-theory via Mordell-Weil torsion

Journal of High Energy Physics, 2018
We explore novel gauge enhancements from abelian to non-simply-connected gauge groups in F-theory. To this end we consider complex structure deformations of elliptic fibrations with a Mordell-Weil group of rank one and identify the conditions under which

From Minkowski to de Sitter in multifield no-scale models

Journal of High Energy Physics, 2019
We show the uniqueness of superpotentials leading to Minkowski vacua of single-field no-scale supergravity models, and the construction of dS/AdS solutions using pairs of these single-field Minkowski superpotentials.

Abelian F-theory models with charge-3 and charge-4 matter

Journal of High Energy Physics, 2018
This paper analyzes U(1) F-theory models admitting matter with charges q = 3 and 4. First, we systematically derive a q = 3 construction that generalizes the previous q = 3 examples.

Uplifts of maximal supergravities and transitions to non-geometric vacua

Journal of High Energy Physics, 2019
We describe a new procedure to obtain consistent backgrounds that uplift vacua and deformations of various maximal gauged supergravities by taking a known solution and performing singular limits along the moduli space of the corresponding 4-dimensional ...

Flowing between string vacua for the critical non-Abelian vortex with a deformation of N=2 Liouville theory

Physical Review D
It has been shown that non-Abelian solitonic vortex string supported in four-dimensional (4D) N=2 supersymmetric QCD (SQCD) with the U(2) gauge group and Nf=4 quark flavors becomes a critical superstring.
