Non-extremal branes

Pablo Bueno, Tomas Ortin, C. S. Shahbazi

We prove that for arbitrary black brane solutions of generic Supergravities there is an adapted system of variables in which the equations of motion are exactly invariant under ele…

On spectrum of ILW hierarchy in conformal field theory II: coset CFT's

M. N. Alfimov, A. V. Litvinov

We study integrable structure of the coset conformal field theory and define the system of Integrals of Motion which depends on external parameters. This system can be viewed as a…

Giant Tachyons in the Landscape

Iosif Bena, Mariana Graña, Stanislav Kuperstein +1

We study the dynamics of localized and fully backreacting anti-D3 branes at the tip of the Klebanov-Strassler geometry. We use a non-supersymmetric version of the Polchinski-Strass…

A semi-holographic model for heavy-ion collisions

Edmond Iancu, Ayan Mukhopadhyay

We develop a semi-holographic model for the out-of-equilibrium dynamics during the partonic stages of an ultrarelativistic heavy-ion collision. The model combines a weakly-coupled…

F-theory on singular spaces

Andres Collinucci, Raffaele Savelli

We propose a framework for treating F-theory directly, without resolving or deforming its singularities. This allows us to explore new sectors of gauge theories, including exotic b…

Effect of the deformation operator in the D1D5 CFT

Zaq Carson, Shaun Hampton, Samir D. Mathur +1

The D1D5 CFT gives a holographic dual description of a near-extremal black hole in string theory. The interaction in this theory is given by a marginal deformation operator, which…

T-branes as branes within branes

Andres Collinucci, Raffaele Savelli

Bound states of 7-branes known as 'T-branes' have properties that defy usual geometric intuition. For instance, the gauge group of n coincident branes may not be U(n). More surpris…

Quiver Tails and N=1 SCFTs from M5-branes

Prarit Agarwal, Ibrahima Bah, Kazunobu Maruyoshi +1

We study a class of four-dimensional N=1 superconformal field theories obtained by wrapping M5-branes on a Riemann surface with punctures. We identify UV descriptions of four-dimen…

The periodic sl(2|1) alternating spin chain and its continuum limit as a bulk Logarithmic Conformal Field Theory at c=0

A. M. Gainutdinov, N. Read, H. Saleur +1

The periodic sl(2|1) alternating spin chain encodes (some of) the properties of hulls of percolation clusters, and is described in the continuum limit by a logarithmic conformal fi…

Global Structure of Curves from Generalized Unitarity Cut of Three-loop Diagrams

Jonathan D. Hauenstein, Rijun Huang, Dhagash Mehta +1

This paper studies the global structure of algebraic curves defined by generalized unitarity cut of four-dimensional three-loop diagrams with eleven propagators. The global structu…

QCD Pomeron from AdS/CFT Quantum Spectral Curve

Mikhail Alfimov, Nikolay Gromov, Vladimir Kazakov

Using the methods of the recently proposed Quantum Spectral Curve (QSC) originating from integrability of Super--Yang-Mills theory we analytically continue the scaling…

Another algebraic variational principle for the spectral curve of matrix models

B. Eynard

We propose an alternative variational principle whose critical point is the algebraic plane curve associated to a matrix model (the spectral curve, i.e. the large limit of the…

Two Virasoro symmetries in stringy warped AdS

Geoffrey Compère, Monica Guica, Maria J. Rodriguez

We study three-dimensional consistent truncations of type IIB supergravity which admit warped AdS solutions. These theories contain subsectors that have no bulk dynamics. We sh…

Metastability in Bubbling AdS Space

Stefano Massai, Giulio Pasini, Andrea Puhm

We study the dynamics of probe M5 branes with dissolved M2 charge in bubbling geometries with SO(4) x SO(4) symmetry. These solutions were constructed by Bena-Warner and Lin-Lunin-…

Generalised geometry for string corrections

André Coimbra, Ruben Minasian, Hagen Triendl +1

We present a general formalism for incorporating the string corrections in generalised geometry, which necessitates the extension of the generalised tangent bundle. Not only are su…

Covariant Noether Charge for Higher Dimensional Chern-Simons Terms

Tatsuo Azeyanagi, R. Loganayagam, Gim Seng Ng +1

We construct a manifestly covariant differential Noether charge for theories with Chern-Simons terms in higher dimensional spacetimes. This is in contrast to Tachikawa's extension…

Pure Gravities via Color-Kinematics Duality for Fundamental Matter

Henrik Johansson, Alexander Ochirov

We give a prescription for the computation of loop-level scattering amplitudes in pure Einstein gravity, and four-dimensional pure supergravities, using the color-kinematics dualit…

Regular 3-charge 4D black holes and their microscopic description

Iosif Bena, C. S. Shahbazi

The perturbative corrections to Type-IIA String Theory compactified on a Calabi-Yau three-fold allow the construction of regular three-charge supersymmetric black hole…

Black-Hole Entropy from Supergravity Superstrata States

Iosif Bena, Masaki Shigemori, Nicholas P. Warner

There are, by now, several arguments that superstrata, which represent D1-D5-P bound states that depend upon arbitrary functions of two variables and that preserve four supersymmet…

Quantum Corrections in String Compactifications on SU(3) Structure Geometries

Mariana Grana, Jan Louis, Ulrich Theis +1

We investigate quantum corrections to the classical four-dimensional low-energy effective action of type II string theory compactified on SU(3) structure geometries. Various method…

Chern-Simons and RG Flows: Contact with Dualities

Antonio Amariti, Claudius Klare

Contact terms in two point functions of global symmetry currents have recently been proposed as a check of Seiberg-like duality in three dimensional supersymmetric field theories.…

Heterotic fluxes and supersymmetry

Ilarion V. Melnikov, Ruben Minasian, Savdeep Sethi

We show that the formal alpha' expansion for heterotic flux vacua is only sensible when flux quantization and the appearance of string scale cycles in the geometry are carefully ta…
