Weak gravity at micron scales from dark bubble cosmology and its cosmological consequences

Ulf Danielsson, Suvendu Giri

The dark bubble model makes a positive cosmological constant natural in string theory, and predicts several new physical phenomena within reach in the near future. In this paper we…

Canonical differential equations and intersection matrices

Claude Duhr, Sara Maggio, Franziska Porkert +3

Differential equations are one of the main approaches to evaluate multi-loop Feynman integrals. The construction of a canonical or -factorised basis for multi-loop int…

Sampling String Vacua Using Generative Models

Moritz Walden, Magdalena Larfors

We apply generative models to a key problem in the string compactification program, namely construction of type IIB string vacua. To this end, we make use of a Bayesian Flow Networ…

Quivers and BPS states in 3d and 4d

Piotr Kucharski, Pietro Longhi, Dmitry Noshchenko +2

We propose a symmetrization relation between BPS quivers encoding 4d theories and symmetric quivers associated to 3d theories. We analyse in detail…

Generalized Symmetries of Non-SUSY and Discrete Torsion String Backgrounds

Noah Braeger, Vivek Chakrabhavi, Jonathan J. Heckman +1

String / M-theory backgrounds with degrees of freedom at a localized singularity provide a general template for generating strongly correlated systems decoupled from lower-dimensio…

On canonical differential equations for Calabi-Yau multi-scale Feynman integrals

Sara Maggio, Yoann Sohnle

We generalise a method recently introduced in the literature, that derives canonical differential equations, to multi-scale Feynman integrals with an underlying Calabi-Yau geometry…

Black Hole Singularities from Holographic Complexity

Vyshnav Mohan

Using a second law of complexity, we prove a black hole singularity theorem. By introducing the notion of trapped extremal surfaces, we show that their existence implies null geode…

Late-Time Saturation of Black Hole Complexity

Friðrik Freyr Gautason, Vyshnav Mohan, Lárus Thorlacius

The holographic complexity of a static spherically symmetric black hole, defined as the volume of an extremal surface, grows linearly with time at late times in general relativity.…
