Taxonomy of infinite distance limits

Journal of High Energy Physics
The Emergent String Conjecture constrains the possible types of light towers in infinite-distance limits in quantum gravity moduli spaces. In this paper, we use these constraints to restrict the geometry of the scalar charge-to-mass vectors ...

The bubble of nothing under T-duality

Journal of High Energy Physics
The bubble of nothing is a solution to Einstein’s equations where a circle shrinks and pinches off smoothly. As such, it is one of the simplest examples of a dynamical cobordism to nothing.

Towards a string realization of the Dark Dimension via T-folds

Journal of High Energy Physics
In this work, we explore the feasibility of realizing the Dark Dimension Scenario through T-fold compactifications on T 5 × S 1, where the base of the internal space S 1 naturally acts as the requisite mesoscopic extra dimension. Utilizing Scherk-Schwarz

Self-tracking solutions for asymptotic scalar fields

Journal of High Energy Physics
We explore the dynamics of pure scalar fields rolling on an exponential potential in the absence of any additional background fluid and demonstrate the existence of self-tracking solutions in which the self-perturbations of the scalar field act as an ...

End of the world boundaries for chiral quantum gravity theories

Journal of High Energy Physics
We describe the construction of large classes of explicit string theory backgrounds corresponding to 6d and 4d chiral theories with end of the world boundaries, and describe the strong coupling phenomena involved in gapping the chiral (but non-anomalous)

Topology change and non-geometry at infinite distance

Journal of High Energy Physics
The distance conjecture diagnoses viable low-energy effective realisations of consistent theories of quantum gravity by examining their breakdown at infinite distance in their parameter space. At the same time, infinite distance points in parameter space

String perturbation theory of Klebanov-Strassler throat

Journal of High Energy Physics
In this work, we develop a tool to study string perturbation theory of the Klebanov-Strassler solution in the large radius approximation based on open-closed superstring field theory.

Modular forms and hierarchical Yukawa couplings in heterotic Calabi-Yau compactifications

Journal of High Energy Physics
We study the modular symmetry in heterotic string theory on Calabi-Yau threefolds. In particular, we examine whether moduli-dependent holomorphic Yukawa couplings are described by modular forms in the context of heterotic string theory with standard ...
