Complex Linear Multiplets and Local Supersymmetry Breaking

Fotis Farakos, Alex Kehagias, Nikolaos Liatsos

We study supersymmetry breaking from a complex linear superfield coupled to 4D N=1 supergravity. The theory has two classically decoupled vacua, one supersymmetric and one with bro…

One-Dimensional Sectors From the Squashed Three-Sphere

Pieter Bomans, Silviu Pufu

Three-dimensional superconformal field theories contain 1d topological sectors consisting of twisted linear combinations of half-BPS local operators that can be i…

Spin Structures and AdS Holography

Nikolay Bobev, Pieter Bomans

We study the importance of spin structures as defining data for 11d supergravity backgrounds of the form AdS with a free orbifold action. For a generic c…

New Dressing Factors for AdS3/CFT2

Sergey Frolov, Alessandro Sfondrini

The worldsheet S matrix of strings on the background is almost entirely fixed by symmetries, up to five functions -- the dressing factors. These must sa…

Super Non-Abelian T-Duality

Daniele Bielli, Silvia Penati, Dmitri Sorokin +1

We analyse super non-Abelian T-duality for principal chiral models, symmetric space sigma models, and semi-symmetric space sigma models for general Lie supergroups. This includes T…

Introductory Notes on Non-linear Electrodynamics and its Applications

Dmitri P. Sorokin

In 1933-1934 Born and Infeld constructed the first non-linear generalization of Maxwell's electrodynamics that turned out to be a remarkable theory in many respects. In 1935 Heisen…

On the Stability of String Theory Vacua

Suvendu Giri, Luca Martucci, Alessandro Tomasiello

Vacuum compactifications may suffer from instabilities under small perturbations or tunnel effects; both are difficult to analyze. In this paper we consider the issue from a higher…

Mirror Thermodynamic Bethe Ansatz for AdS3/CFT2

Sergey Frolov, Alessandro Sfondrini

We consider superstrings on the pure-Ramond-Ramond background. Using the recently-proposed dressing factors for the worldsheet S matrix, we formulate th…

Massless S matrices for AdS3/CFT2

Sergey Frolov, Alessandro Sfondrini

The AdS3/CFT2 correspondence features massless non-relativistic modes on the string worldsheet in lightcone gauge. We study in detail these excitations and highlight how they natur…

String gravity in

Pablo A. Cano, Alejandro Ruipérez

We revisit the four-dimensional theory of gravity that arises from string theory with higher-derivative corrections. By compactifying and truncating the ten-dimensional effective a…

New N=1 AdS solutions of type IIB supergravity

David Berman, Thomas Fischbacher, Gianluca Inverso

We construct analytically a new family of supersymmetric AdS solutions of IIB supergravity, with the internal space provided by a deformed . The solutions preser…

Positive energy and non-SUSY flows in ISO(7) gauged supergravity

Giuseppe Dibitetto

We consider maximal gauged supergravity in 4D with ISO(7) gauge group, which arises from a consistent truncation of massive IIA supergravity on a six-sphere. Within its G invar…

Universe as Klein-Gordon Eigenstates

Marco Matone

We formulate Friedmann's equations as second-order linear differential equations. This is done using techniques related to the Schwarzian derivative that selects the -times $t_β…

The unbearable lightness of charged gravitini

Gianguido Dall'Agata, Maxim Emelin, Fotis Farakos +1

We prove that charged gravitini cannot have parametrically small or vanishing Lagrangian mass in de Sitter vacua of extended supergravity while respecting the magnetic weak gravity…

BPS Algebras in 2D String Theory

Sarah M. Harrison, Natalie M. Paquette, Daniel Persson +1

We discuss a set of heterotic and type II string theory compactifications to 1+1 dimensions that are characterized by factorized internal worldsheet CFTs of the form $V_1\otimes \b…

Deformations of Supergravity and Supersymmetry Anomalies

Markus B. Fröb, Camillo Imbimbo, Nicolò Risso

We present a BRST analysis of supersymmetry anomalies of supersymmetric quantum field theories with anomalous R symmetry. To this end, we consider the coupling of…

Thermodynamics of accelerating and supersymmetric black holes

Davide Cassani, Jerome P. Gauntlett, Dario Martelli +1

We study the thermodynamics of black hole solutions of Einstein-Maxwell theory that are accelerating, rotating, and carry electric and magnetic charges. We focus on the cla…

EFT and the SUSY Index on the 2nd Sheet

Davide Cassani, Zohar Komargodski

The counting of BPS states in four-dimensional theories has attracted a lot of attention in recent years. For superconformal theories, these states are in one-to-one c…

Slow and Safe Gravitinos

Emilian Dudas, Marcos A. G. Garcia, Yann Mambrini +3

It has been argued that supergravity models of inflation with vanishing sound speeds, , lead to an unbounded growth in the production rate of gravitinos. We consider several m…
