Came into existence after 10^500 conjectures. Eats EFTs for breakfast. UV complete or surrender. Resistance is futile.

On BPS Branes

We study supersymmetric BPS branes (BPS-B) in supergravity theories. Some of these states are anticipated by BPS black-brane (BPS-BB) solutions of supergravity. In particular, we define and...

Testing F-theory GUTs with the Axiverse

We show that axions coupled to photons in F-theory Grand Unified Theories (GUTs) satisfy the coupling-to-mass relation $g_{aγ}/m_a \leq C\, \frac{α_{\rm em}}{2π}\frac{1}{m_πf_π}$,...

Stochastic Survival near Swampland Boundaries

Swampland and compactification data tell us where EFT control can fail; stochastic cosmology asks which histories survive near that edge. We turn this question into a survival problem for...

Supersymmetry, Large Extra Dimensions and the Gravitino Conjecture

We investigate whether the absence of experimental signals for supersymmetry and extra dimensions can be understood as a correlated phenomenon. Assuming the Gravitino Conjecture, we study the...

Gravity Decoupling and Axionic Shift Symmetries

We analyse the rôle of approximate axionic shift symmetries in gravity-decoupling limits arising in type II Calabi-Yau compactifications. Associated with each shift symmetry there is an axionic...

EFTs with Symmetric Moduli Spaces: the Landscape and the Swampland

The Swampland Distance Conjecture (SDC) states that, for any infinite-distance limit in the moduli space of a quantum gravity effective field theory (EFT), there should exist an infinite tower of...

Sharpening the Supersymmetric Axion Weak Gravity Conjecture

The Axion Weak Gravity Conjecture provides one of the most effective quantum gravity tools for constraining particle physics and cosmology, but it has long been thought of as a slightly fuzzy...

Constraining Spatial Curvature with Priors from Swampland Conjectures

We study a string-motivated theoretical prior on the quintessential dark energy model with exponential potential, \( V(ϕ) = V_0 e^{-λϕ} \), allowing for non-zero spatial curvature....

The Equivalence Principle at High Energies Completes the Spectrum

We prove a version of the completeness hypothesis that follows from the coexistence of symmetry and gravity: tree-level gravitational scattering mandates single-particle states in all possible...

Uniqueness of D=8 minimal supergravity with two vector multiplets

There exist only four known string theories with minimal supersymmetry in eight dimensions, whose low energy effective descriptions are given by minimal supergravity coupled to $l=18$, $10$, or...

A missing link: Brane networks and the Cobordism Conjecture

The absence of global symmetries in a quantum gravity theory often requires the introduction of (new) symmetry-breaking defects, which appear as singular objects in the low-energy description....

Isolated Critical Points for Scherk-Schwarz Compactifications of M-theory

We consider Scherk-Schwarz compactifications of M-theory (toroidal compactifications with a non-trivial spin structure) in various dimensions and find isolated critical points of the potential on...

We study the topological properties of bordisms interpolating between different 9d gauged supergravities obtained from compactification of type IIB string theory on $\mathbb{S}^1$ with a...

String probes, simple currents, and the no global symmetries conjecture

Center one-form symmetries in consistent quantum gravity theories are expected to be either broken or gauged, thereby determining the global form of the gauge group. We shed light on this...

Analytic Bootstrap of the Veneziano Amplitude

We analytically prove, to all orders, that the Veneziano amplitude is the unique outcome of a dual bootstrap based on dispersive sum rules, unitarity, and a small amount of additional stringy...

Broken and restored: a holographic constraint for AdS vacua with orbifolds

It has been suggested that families of weakly-coupled AdS vacua with a large-$N$ holographic dual must satisfy non-trivial consistency requirements, which amount to the vanishing of certain cubic...
