Shapes of gravity: Tensor non-Gaussianity and massive spin-2 fields

Garrett Goon, Kurt Hinterbichler, Austin Joyce +1

If the graviton is the only high spin particle present during inflation, then the form of the observable tensor three-point function is fixed by de Sitter symmetry at leading order…

The Swampland Distance Conjecture for Kahler moduli

Pierre Corvilain, Thomas W. Grimm, Irene Valenzuela

The Swampland Distance Conjecture suggests that an infinite tower of modes becomes exponentially light when approaching a point that is at infinite proper distance in field space.…

Black resonators and geons in AdS

Takaaki Ishii, Keiju Murata

We construct dynamical black hole solutions with a helical symmetry in AdS, called black resonators, as well as their horizonless limits, called geons. We introduce a cohomogen…

Quantum Corrections to Central Charges and Supersymmetric Casimir Energy in AdS/CFT

Arash Arabi Ardehali, Finn Larsen, James T. Liu +1

We study the Casimir energy of bulk fields in AdS and its relation to subleading terms in the central charge of the dual CFT. Computing both sides of the standard CFT r…

Inverse Anisotropic Catalysis in Holographic QCD

Umut Gursoy, Matti Jarvinen, Govert Nijs +1

We investigate the effects of anisotropy on the chiral condensate in a holographic model of QCD with a fully backreacted quark sector at vanishing chemical potential. The high temp…

Infinite Distance Networks in Field Space and Charge Orbits

Thomas W. Grimm, Chongchuo Li, Eran Palti

The Swampland Distance Conjecture proposes that approaching infinite distances in field space an infinite tower of states becomes exponentially light. We study this conjecture for…

Magnetized orbifolds and localized flux

Wilfried Buchmuller, Markus Dierigl, Yoshiyuki Tatsuta

Magnetized orbifolds play an important role in compactifications of string theories and higher-dimensional field theories to four dimensions. Magnetic flux leads to chiral fermions…

A geometric dual of -extremization

Christopher Couzens, Jerome P. Gauntlett, Dario Martelli +1

We consider supersymmetric AdS and AdS solutions of type IIB and supergravity, respectively, that are holographically dual to SCFTs with $(0,2)…

Effective Field Theory of Black Hole Quasinormal Modes in Scalar-Tensor Theories

Gabriele Franciolini, Lam Hui, Riccardo Penco +2

The final ringdown phase in a coalescence process is a valuable laboratory to test General Relativity and potentially constrain additional degrees of freedom in the gravitational s…

Thermodynamic bootstrap program for integrable QFT's: Form factors and correlation functions at finite energy density

Axel Cortés Cubero, Miłosz Panfil

We study the form factors of local operators of integrable QFT's between states with finite energy density. These states arise, for example, at finite temperature, or from a genera…

A new class of SYK-like models with maximal chaos

Eric Marcus, Stefan Vandoren

We investigate a model closely related to both the original Sachdev-Ye-Kitaev (SYK) model and the supersymmetric SYK model. It consists of real Majorana fermion…

Slow relaxation and diffusion in holographic quantum critical phases

Richard A. Davison, Simon A. Gentle, Blaise Goutéraux

The dissipative dynamics of strongly interacting systems are often characterised by the timescale set by the inverse temperature . We show that near a class of…

Four-dimensional black hole entropy from F-theory

Thomas W. Grimm, Huibert het Lam, Kilian Mayer +1

We study the central charges and levels of a two-dimensional superconformal field theory describing four-dimensional BPS black holes in F-theory. These arise from D3-bran…

Dai-Freed anomalies in particle physics

Iñaki García-Etxebarria, Miguel Montero

Anomalies can be elegantly analyzed by means of the Dai-Freed theorem. In this framework it is natural to consider a refinement of traditional anomaly cancellation conditions, whic…

Fluctuations in non-conformal holographic plasma at criticality

Panagiotis Betzios, Umut Gürsoy, Matti Järvinen +1

We continue the study initiated in [arXiv:1708.02252] of the fluctuations of a strongly-coupled non-conformal plasma described holographically by Einstein gravity coupled to a dila…

BRST quantization and equivariant cohomology: localization with asymptotic boundaries

Bernard de Wit, Sameer Murthy, Valentin Reys

We develop BRST quantization of gauge theories with a soft gauge algebra on spaces with asymptotic boundaries. The asymptotic boundary conditions are imposed on background fields,…

Behind Horndeski: Structurally Robust Higher Derivative EFTs

Luca Santoni, Enrico Trincherini, Leonardo G. Trombetta

Higher derivative scalar interactions can give rise to interesting cosmological scenarios. We present a complete classification of such operators that can yield sizeable effects wi…

Phase Space Non-commutativity and its Stability

Paolo Castorina, Alfredo Guerrera, Tomislav Prokopec

We consider a generalised non-commutative space-time in which non-commutativity is extended to all phase space variables. If strong enough, non-commutativity can affect stability o…

Dynamical gauge fields and anomalous transport at strong coupling

Angel Domingo Gallegos, Umut Gürsoy

Anomalous transport coefficients are known to be universal in the absence of dynamical gauge fields. We calculate the corrections to these universal values due to dynamical gluon f…

Exotic holographic RG flows at finite temperature

U. Gürsoy, E. Kiritsis, F. Nitti +1

Black hole solutions and their thermodynamics are studied in Einstein-scalar theories. The associated zero-temperature solutions are non-trivial holographic RG flows. These include…

Effective field theory of time-translational symmetry breaking in nonequilibrium open system

Masaru Hongo, Suro Kim, Toshifumi Noumi +1

We develop the effective field theoretical (EFT) approach to time-translational symmetry breaking of nonequilibrium open systems based on the Schwinger-Keldysh formalism. In the Sc…

Flux compactifications and naturalness

Wilfried Buchmuller, Markus Dierigl, Emilian Dudas

Free massless scalars have a shift symmetry. This is usually broken by gauge and Yukawa interactions, such that quantum corrections induce a quadratically divergent mass term. In t…

Global tensor-matter transitions in F-theory

Markus Dierigl, Paul-Konstantin Oehlmann, Fabian Ruehle

We use F-theory to study gauge algebra preserving transitions of 6d supergravity theories that are connected by superconformal points. While the vector multiplets remain unchanged,…
