Lattice regularisation of a non-compact boundary conformal field theory

Niall F. Robertson, Jesper Lykke Jacobsen, Hubert Saleur

Non-compact Conformal Field Theories (CFTs) are central to several aspects of string theory and condensed matter physics. They are characterised, in particular, by the appearance o…

All AdS solutions in 10 and 11 dimensions

Andrea Legramandi, Gabriele Lo Monaco, Niall T. Macpherson

We classify AdS solutions preserving supersymmetry in ten and eleven dimensions and find the local form of each of them. These include the AdSS$^6…

Sequential deconfinement in gauge theories

Sergio Benvenuti, Ivan Garozzo, Gabriele Lo Monaco

We consider gauge theories with fundamental matter plus a single field in a rank- representation. Using iteratively a process of "deconfinement" of the…

Supersymmetry and Superstrata in Three Dimensions

Anthony Houppe, Nicholas P. Warner

We analyze the supersymmetry transformations of gauged supergravity coupled to extra hypermultiplets in three dimensions, and find large families of smooth BPS solutions th…

Oh, wait, O8 de Sitter may be unstable!

Iosif Bena, G. Bruno De Luca, Mariana Graña +1

We analyze the stability of four-dimensional de Sitter vacua constructed by compactifying massive Type IIA supergravity in the presence of two O8 sources [1]. When embedded in Stri…

Determinant Form of Correlators in High Rank Integrable Spin Chains via Separation of Variables

Nikolay Gromov, Fedor Levkovich-Maslyuk, Paul Ryan

In this paper we take further steps towards developing the separation of variables program for integrable spin chains with gl(N) symmetry. By finding, for the first time, the matri…

Loop-Level Double-Copy for Massive Quantum Particles

John Joseph M. Carrasco, Ingrid A. Vazquez-Holm

We find that scattering amplitudes in massive scalar QCD can manifest the duality between color and kinematics at loop-level. Specifically we construct the one-loop integrands for…

The dimension-shift conjecture for one-loop amplitudes

Ruth Britto, Guy R. Jehu, Andrea Orta

A conjecture made by Bern, Dixon, Dunbar, and Kosower asserts a simple dimension-shifting relationship between the one-loop structure of N = 4 MHV amplitudes and all-plus helicity…

Positive Moments for Scattering Amplitudes

Brando Bellazzini, Joan Elias Miró, Riccardo Rattazzi +2

We find the complete set of conditions satisfied by the forward scattering amplitude in unitarity and causal theories. These are based on an infinite set of energy dependen…

On supersymmetric AdS solutions of Type II

Achilleas Passias, Daniël Prins

We classify supersymmetric warped AdS backgrounds of Type IIA and Type IIB supergravity with non-constant dilaton, generic RR fluxes and magnetic NSNS flux, in ter…

Fuzzballs and Observations

Daniel R. Mayerson

The advent of gravitational waves and black hole imaging has opened a new window into probing the horizon scale of black holes. An important question is whether string theory resul…

Flops, Gromov-Witten Invariants and Symmetries of Line Bundle Cohomology on Calabi-Yau Three-folds

Callum R. Brodie, Andrei Constantin, Andre Lukas

The zeroth line bundle cohomology on Calabi-Yau three-folds encodes information about the existence of flop transitions and the genus zero Gromov-Witten invariants. We illustrate t…

Bounds on multiscalar CFTs in the epsilon expansion

Matthijs Hogervorst, Chiara Toldo

We study fixed points with N scalar fields in dimensions to leading order in using a bottom-up approach. We do so by analyzing O(N) invariants of th…

The action of the Virasoro algebra in quantum spin chains. I. The non-rational case

Linnea Grans-Samuelsson, Jesper Lykke Jacobsen, Hubert Saleur

We investigate the action of discretized Virasoro generators, built out of generators of the lattice Temperley-Lieb algebra ("Koo-Saleur generators"[arXiv:hep-th/9312156]), in the…

The Tadpole Problem

Iosif Bena, Johan Blåbäck, Mariana Graña +1

We examine the mechanism of moduli stabilization by fluxes in the limit of a large number of moduli. We conjecture that one cannot stabilize all complex-structure moduli in F-theor…

The Harder They Fall, the Bigger They Become: Tidal Trapping of Strings by Microstate Geometries

Emil J. Martinec, Nicholas P. Warner

We consider the fate of a massless (or ultra-relativistic massive) string probe propagating down the BTZ-like throat of a microstate geometry in the D1-D5 system. Far down the thro…
