Born-Infeld Supermaze Waves

Iosif Bena, Raphaël Dulac

The entropy of the supersymmetric D2-D4-P black hole comes at weak coupling from D2-brane strips stretched between parallel D4 branes and carrying momentum waves. We use the DBI ac…

Tensionless strings on orbifolds

Matthias R. Gaberdiel, Bin Guo, Samir D. Mathur

The bound state of one NS5 brane (wrapped on a ) and NS1-branes has two dual descriptions: its low-energy dynamics is described by the symmetric orbifold of $\mat…

The Subtle Simplicity of Cosmological Correlators

Chandramouli Chowdhury, Arthur Lipstein, Jiajie Mei +2

We investigate cosmological correlators for conformally coupled theory in four-dimensional de Sitter space. These \textit{in-in} correlators differ from scattering amplitudes…

Missing local operators, zeros, and twist-4 trajectories

Johan Henriksson, Petr Kravchuk, Brett Oertel

The number of local operators in a CFT below a given twist grows with spin. Consistency with analyticity in spin then requires that at low spin, infinitely many Regge trajectories…

Casimir Forces in CFT with Defects and Boundaries

Philippe Brax, Sylvain Fichet

We investigate the quantum forces occurring between the defects and/or boundaries of a conformal field theory (CFT). We propose to model imperfect defects and boundaries as localiz…

Deep learning complete intersection Calabi-Yau manifolds

Harold Erbin, Riccardo Finotello

We review advancements in deep learning techniques for complete intersection Calabi-Yau (CICY) 3- and 4-folds, with the aim of understanding better how to handle algebraic topologi…

Fourier Calculus from Intersection Theory

Giacomo Brunello, Giulio Crisanti, Mathieu Giroux +2

Building on recent advances in studying the co-homological properties of Feynman integrals, we apply intersection theory to the computation of Fourier integrals. We discuss applica…

Bootstrapping multi-wound twist effects in symmetric orbifold CFTs

Bin Guo, Shaun D. Hampton

We investigate the effects of the twist-2 operator in 2D symmetric orbifold CFTs. The twist operator can join together a twist- state and a twist- state, creating a twist-$(M…

Anomalous higher order Ward identities in tensorial group field theories without closure constraint

Bio Wahabou Kpera, Vincent Lahoche, Dine Ousmane Samary +1

The Ward-Takahashi identities are considered as the generalization of the Noether currents available to quantum field theory and include quantum fluctuation effects. Usually, they…

The correspondence between rotating black holes and fundamental strings

Nejc Čeplak, Roberto Emparan, Andrea Puhm +1

The correspondence principle between strings and black holes is a general framework for matching black holes and massive states of fundamental strings at a point where their physic…

Energy correlations in heavy states

D. Chicherin, G. P. Korchemsky, E. Sokatchev +1

We study energy correlations in states created by a heavy operator acting on the vacuum in a conformal field theory. We argue that the energy correlations in such states exhibit tw…

Consistency of eight-dimensional supergravities: Anomalies, Lattices and Counterterms

Bing-Xin Lao, Ruben Minasian

We reexamine the question of quantum consistency of supergravities in eight dimensions. Theories with 16 supercharges suffer from the anomalies under the action of its discrete mod…

Flat F-theory and friends

Peng Cheng, Ilarion V. Melnikov, Ruben Minasian

We discuss F-theory backgrounds associated to flat torus bundles over Ricci-flat manifolds. In this setting the F-theory background can be understood as a IIB orientifold with a la…

Momentum in Single-trace Holography

Soumangsu Chakraborty, Amit Giveon, David Kutasov

We extend the study of 2006.13249, 2303.12422 to black strings with general momentum, and discuss their interpretation in single-trace deformed .

Integrable Feynman Graphs and Yangian Symmetry on the Loom

Vladimir Kazakov, Fedor Levkovich-Maslyuk, Victor Mishnyakov

We present significant evidence that the powerful property of Yangian invariance extends to a new large class of conformally invariant Feynman integrals. Our results apply to plana…
