abstract
The tachyon-free nonsupersymmetric string theories in ten dimensions have dilaton tadpoles which forbid a Minkowski vacuum. We determine the maximally symmetric backgrounds for the $USp(32)$ Type I string and the $SO(16)\times SO(16)$ heterotic string. The static solutions exhibit nine dimensional Poincar\'e symmetry and have finite 9D Planck and Yang-Mills constants. The low energy geometry is given by a ten dimensional manifold with two boundaries separated by a finite distance which suggests a spontaneous compactification of the ten dimensional string theory.

R7-branes and AdS$_{\text{9}}$ solutions in type IIB
Explicit analytic 7-brane solutions in type IIB are built with AdS9 near-horizon geometry, and imposing the reflection monodromy tau -> -bar tau selects a subclass proposed as R7-branes.

$\text{AdS}_D\times I$ solutions in axio-dilaton gravity
The authors reformulate the equations of motion for AdS_D × I solutions in axio-dilaton gravity as a first-order autonomous dynamical system, identify fixed points and analytic solutions for arbitrary D including in t...

Alice in Warpland: KK modes, Warped Compactifications and the Swampland
In codimension-one warped compactifications with exponential potentials, the KK mass decay rate λ_KK is reduced by warping but still satisfies the Sharpened Distance Conjecture precisely when the higher-dimensional po...

Brane annihilation in non-supersymmetric strings
Non-supersymmetric AdS×S flux vacua in three string models decay by flux-reducing tunneling whose semi-classical rates match brane-instanton estimates from D1- or NS5-branes.

AdS$_9$ solutions in type II supergravities
New analytic AdS9 solutions in type IIB with finite action and central charge, numerical massive IIA solutions with diverging action, and perturbative dS9 solutions are constructed in type II supergravities.

Bordisms between 9d type IIB supergravities and commutator widths of duality groups
Proposes a refinement of the Swampland Cobordism Conjecture for Ω1(BG) with duality bundle G, where diverging commutator width of G requires infinitely many duality defects to realize monodromies via gravitational solitons.

Non-supersymmetric strings on AdS$_3$: a world-sheet perspective
On AdS3×S3×S3×S1, a Wilson-line deformation of the Spin(16)×Spin(16)⋊Z2 heterotic string produces a level-matched tachyon, so the classical moduli space contains unstable regions.

Relative Quantum Gravity: Localized Gravity and the Swampland
Localized gravity theories can violate swampland constraints, but satisfy them when defined relative to a higher-dimensional gravity completion, dubbed relative quantum gravity.

Anomaly Inflow and Gauge Group Topology in the 10d Sugimoto String Theory
Anomaly inflow on Sugimoto model branes supports the conclusion that the 10d gauge group is Sp(16)/Z2, and the same inflow matching rules out most alternative chiral spectra.
