One-modulus Calabi-Yau fourfold reductions with higher-derivative terms

Thomas W. Grimm, Kilian Mayer, Matthias Weissenbacher

In this note we consider M-theory compactified on a warped Calabi-Yau fourfold including the eight-derivative terms in the eleven-dimensional action known in the literature. We dim…

Partially Massless Fields During Inflation

Daniel Baumann, Garrett Goon, Hayden Lee +1

The representation theory of de Sitter space allows for a category of partially massless particles which have no flat space analog, but could have existed during inflation. We stud…

Lifshitz entanglement entropy from holographic cMERA

Simon A. Gentle, Stefan Vandoren

We study entanglement entropy in free Lifshitz scalar field theories holographically by employing the metrics proposed by Nozaki, Ryu and Takayanagi in \cite{Nozaki:2012zj} obtaine…

Soft Theorems For Shift-Symmetric Cosmologies

Bernardo Finelli, Garrett Goon, Enrico Pajer +1

We derive soft theorems for single-clock cosmologies that enjoy a shift symmetry. These so-called consistency conditions arise from a combination of a large diffeomorphism and the…

Saturation of the Quantum Null Energy Condition in Far-From-Equilibrium Systems

Christian Ecker, Daniel Grumiller, Wilke van der Schee +1

The Quantum Null Energy Condition (QNEC) is a new local energy condition that a general Quantum Field Theory (QFT) is believed to satisfy, relating the classical null energy condit…

Complexity is Simple

William Cottrell, Miguel Montero

In this note we investigate the role of Lloyd's computational bound in holographic complexity. Our goal is to translate the assumptions behind Lloyd's proof into the bulk language.…

Chiral anomalies on a circle and their cancellation in F-theory

Pierre Corvilain, Thomas W. Grimm, Diego Regalado

We study in detail how four-dimensional local anomalies manifest themselves when the theory is compactified on a circle. By integrating out the Kaluza-Klein modes in a way that pre…

Hydrodynamic Modes of Homogeneous and Isotropic Fluids

Jan de Boer, Jelle Hartong, Niels A. Obers +2

Relativistic fluids are Lorentz invariant, and a non-relativistic limit of such fluids leads to the well-known Navier-Stokes equation. However, for fluids moving with respect to a…

Perfect Fluids

Jan de Boer, Jelle Hartong, Niels A. Obers +2

We develop a new theory of perfect fluids with translation and rotation symmetry, which is also applicable in the absence of any type of boost symmetry. It involves introducing a n…

A Note on the WGC, Effective Field Theory and Clockwork within String Theory

Luis E. Ibanez, Miguel Montero

It has been recently argued that Higgsing of theories with gauge interactions consistent with the Weak Gravity Conjecture (WGC) may lead to effective field theories parame…

Chaotic strings in AdS/CFT

Jan de Boer, Eva Llabrés, Juan F. Pedraza +1

Holographic theories with classical gravity duals are maximally chaotic; i.e., they saturate the universal bound on the rate of growth of chaos. It is interesting to ask whether th…

four dimensional field theories

Iñaki García-Etxebarria, Diego Regalado

We briefly review a class of four dimensional field theories constructed by taking a quotient of SYM with gauge group . The quotient involves a…

Quasi-normal modes of a strongly coupled non-conformal plasma and approach to criticality

Panagiotis Betzios, Umut Gürsoy, Matti Järvinen +1

We study fluctuations around equilibrium in a class of strongly interacting non-conformal plasmas using holographic techniques. In particular we calculate the quasi-normal mode spe…

Are tiny gauge couplings out of the Swampland?

Miguel Montero

There is significant evidence suggesting that continuous global symmetries are always gauged in quantum gravity. However, very weakly gauged symmetries seem global to an effective…

Strongly-coupled anisotropic gauge theories and holography

Dimitrios Giataganas, Umut Gürsoy, Juan F. Pedraza

We initiate a non-perturbative study of anisotropic, non-conformal and confining gauge theories that are holographically realized in gravity by generic Einstein-Axion-Dilaton syste…

Tweaking one-loop determinants in AdS

Alejandra Castro, Cynthia Keeler, Phillip Szepietowski

We revisit the subject of one-loop determinants in AdS gravity via the quasinormal mode method. Our goal is to evaluate a one-loop determinant with chiral boundary conditions f…

Holographic QCD in the Veneziano limit at finite Magnetic Field and Chemical Potential

Umut Gursoy, Matti Jarvinen, Govert Nijs

We investigate the phase diagram of QCD-like gauge theories at strong coupling at finite magnetic field , temperature and baryon chemical potential using the improved ho…

Constraining Neutrino Masses, the Cosmological Constant and BSM Physics from the Weak Gravity Conjecture

Luis E. Ibanez, Victor Martin-Lozano, Irene Valenzuela

It is known that there are AdS vacua obtained from compactifying the SM to 2 or 3 dimensions. The existence of such vacua depends on the value of neutrino masses through the Casimi…
