Moduli trapping mechanism in modular flavor symmetric models

open access: yesJournal of High Energy Physics, 2023
We discuss how the moduli in modular flavor symmetric models dynamically select enhanced symmetry points at which the residual modular symmetry renders extra matter fields massless.

A systematic approach to Kähler moduli stabilisation

open access: yesJournal of High Energy Physics, 2020
Achieving full moduli stabilisation in type IIB string compactifications for generic Calabi-Yau threefolds with hundreds of Kähler moduli is notoriously hard.

Kähler-Einstein metrics: Old and New

open access: yesComplex Manifolds, 2017
We present classical and recent results on Kähler-Einstein metrics on compact complex manifolds, focusing on existence, obstructions and relations to algebraic geometric notions of stability (K-stability).

Non-abelian vortices on CP^1 and Grassmannians [PDF]

open access: yes, 2013
Many properties of the moduli space of abelian vortices on a compact Riemann surface are known. For non-abelian vortices the moduli space is less well understood. Here we consider non-abelian vortices on the Riemann sphere CP^1, and we study their moduli

Mixed moduli in 3d N $$ \mathcal{N} $$ = 4 higher-genus quivers

open access: yesJournal of High Energy Physics, 2023
We analyze exactly marginal deformations of 3d N $$ \mathcal{N} $$ = 4 Lagrangian gauge theories, especially mixed-branch operators with both electric and magnetic charges.

Heterotic moduli stabilisation [PDF]

open access: yesJournal of High Energy Physics, 2013
Abstract We perform a systematic analysis of moduli stabilisation for weakly coupled heterotic string theory compactified on internal manifolds which are smooth Calabi-Yau three-folds up to α′ effects. We first review how to stabilise all the geometric and gauge bundle moduli in a supersymmetric way by including fractional fluxes ...

Closed strings and moduli in AdS3/CFT2

open access: yesJournal of High Energy Physics, 2018
String theory on AdS3 × S3 × T4 has 20 moduli. We investigate how the perturbative closed string spectrum changes as we move around this moduli space in both the RR and NSNS flux backgrounds. We find that, at weak string coupling, only four of the moduli

Beauty is Attractive: Moduli Trapping at Enhanced Symmetry Points [PDF]

open access: yes, 2004
We study quantum effects on moduli dynamics arising from the production of particles which are light at special points in moduli space. The resulting forces trap the moduli at these points, which often exhibit enhanced symmetry. Moduli trapping occurs in

ON SINGULARITIES OF QUIVER MODULI [PDF]

open access: yesGlasgow Mathematical Journal, 2010
AbstractAny moduli space of representations of a quiver (possibly with oriented cycles) has an embedding as a dense open subvariety into a moduli space of representations of a bipartite quiver having the same type of singularities. A connected quiver is Dynkin or extended Dynkin if and only if all moduli spaces of its representations are smooth.

Supersymmetric moduli stabilization and high-scale inflation

open access: yesPhysics Letters B, 2014
We study the back-reaction of moduli fields on the inflaton potential in generic models of F-term inflation. We derive the moduli corrections as a power series in the ratio of Hubble scale and modulus mass.
