Quantum Gravity on AdSS from CFT: Bootstrapping

Francesco Aprile, Hynek Paul, Michele Santagata

We consider the simplest four-point scattering amplitude of tensor multiplets in six-dimensional (2,0) supergravity on AdSS. Using crossing symmetry and the c…

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.…

Symplectic cuts and open/closed strings II

Luca Cassia, Pietro Longhi, Maxim Zabzine

In arXiv:2306.07329 we established a connection between symplectic cuts of Calabi-Yau threefolds and open topological strings, and used this to introduce an equivariant deformation…

Weak -manifolds and scale separation in M-theory from type IIA backgrounds

Vincent Van Hemelryck

This work provides evidence for the existence of supersymmetric and scale-separated AdS vacua in M-theory of the Freund-Rubin type. The internal space has weak -holonomy,…

Charged Nariai black holes on the dark bubble

Ulf Danielsson, Vincent Van Hemelryck

In this paper, we realise the charged Nariai black hole on a braneworld from a nucleated bubble in AdS, known as the dark bubble model. Geometrically, the black hole takes the…

Proof of 5D AGT conjecture at

Qian Shen, Zi-Hao Huang, Shao-Ping Hu +2

In this paper, we give a proof of 5D AGT conjecture at , where the gauge theory side is one dimension higher than the original 4D case, and corresponds to the q-deformat…

Super Yang-Mills on Branched Covers and Weighted Projective Spaces

Roman Mauch, Lorenzo Ruggeri

In this work we conjecture the Coulomb branch partition function, including flux and instanton contributions, for the vector multiplet on weighted projective space…

Advanced tools for basis decompositions of genus-one string integrals

Yong Zhang

In string theories, one-loop scattering amplitudes are characterized by integrals over genus-one surfaces using the Kronecker-Eisenstein series. A recent methodology proposed a gen…

Remarks on Geometric Engineering, Symmetry TFTs and Anomalies

Michele Del Zotto, Shani Nadir Meynet, Robert Moscrop

Geometric engineering is a collection of tools developed to establish dictionaries between local singularities in string theory and (supersymmetric) quantum fields. Extended operat…

Disconnected gauge groups in the infrared

Guillermo Arias-Tamargo, Mario De Marco

Gauging a discrete 0-form symmetry of a QFT is a procedure that changes the global form of the gauge group but not its perturbative dynamics. In this work, we study the Seiberg-Wit…

A double copy from twisted (co)homology at genus one

Rishabh Bhardwaj, Andrzej Pokraka, Lecheng Ren +1

We study the twisted (co)homology of a family of genus-one integrals -- the so called Riemann-Wirtinger integrals. These integrals are closely related to one-loop string amplitudes…

Connecting flux vacua through scalar field excursions

Gary Shiu, Flavio Tonioni, Vincent Van Hemelryck +1

We show how flux vacua that differ from each other in flux quanta can be seen as different vacua in a single scalar potential of an enlarged field space, which resolves the separat…

Shedding light on dark bubble cosmology

Ivano Basile, Ulf Danielsson, Suvendu Giri +1

Dark bubble cosmology is an alternative paradigm to compactification, which can circumvent issues of moduli stabilization and scale separation. In this paper we investigate how ele…

A new vista on the Heterotic Moduli Space from Six and Three Dimensions
