Black holes with halos

Ruben Monten, Chiara Toldo

We present new AdS4 black hole solutions in N = 2 gauged supergravity coupled to vector and hypermultiplets. We focus on a particular consistent truncation of M-theory on the homog…

On rectangular HOMFLY for twist knots

Ya. Kononov, A. Morozov

As a new step in the study of rectangularly-colored knot polynomials, we reformulate the prescription of arXiv:1606.06015 for twist knots in the double-column representations $R=[r…

Betti multiplets, flows across dimensions and c-extremization

Antonio Amariti, Chiara Toldo

We consider 4d N=1 SCFTs, topologically twisted on compact constant curvature Riemann surfaces, giving rise to 2d N=(0,2) SCFTs. The exact R-current of these 2d SCFT extremizes the…

A Modern Approach to Superradiance

Solomon Endlich, Riccardo Penco

In this paper, we provide a simple and modern discussion of rotational superradiance based on quantum field theory. We work with an effective theory valid at scales much larger tha…

Random Field Theories in The Mirror Quintic Moduli Space

Kate Eckerle, Brian Greene

We investigate the distribution of field theories that arise from the low energy limit of flux vacua built on type IIB string theory compactified on the mirror quintic. For a large…

Inflation Expels Runaways

Thomas C. Bachlechner

We argue that moduli stabilization generically restricts the evolution following transitions between weakly coupled de Sitter vacua and can induce a strong selection bias towards i…

Lorentzian Condition in Holographic Cosmology

Thomas Hertog, Ruben Monten, Yannick Vreys

We derive a sufficient set of conditions on the Euclidean boundary theory in dS/CFT for it to predict classical, Lorentzian bulk evolution at large spatial volumes. Our derivation…

Positivity Constraints for Pseudo-linear Massive Spin-2 and Vector Galileons

James Bonifacio, Kurt Hinterbichler, Rachel A. Rosen

We derive analyticity constraints on a nonlinear ghost-free effective theory of a massive spin-2 particle known as pseudo-linear massive gravity, and on a generalized theory of a m…

First Sound in Holographic Superfluids at Zero Temperature

Angelo Esposito, Sebastian Garcia-Saenz, Riccardo Penco

Within the context of AdS/CFT, the gravity dual of an s-wave superfluid is given by scalar QED on an asymptotically AdS spacetime. While this conclusion is vastly supported by nume…

A geometric formulation of exceptional field theory

Pascal du Bosque, Falk Hassler, Dieter Lust +1

We formulate the full bosonic SL(5) exceptional field theory in a coordinate-invariant manner. Thereby we interpret the 10-dimensional extended space as a manifold with $\mathrm{SL…

Thermodynamics of spinning AdS4 black holes in gauged supergravity

Chiara Toldo

In this paper we study the thermodynamics of rotating black hole solutions arising from four-dimensional gauged N=2 supergravity. We analyze two different supergravity models, char…

A magnetically induced quantum phase transition in holography

A. Gnecchi, U. Gursoy, O. Papadoulaki +1

We investigate quantum phase transitions in a 2+1 dimensional gauge theory at finite chemical potential and magnetic field . The gravity dual is based on 4D …

Equivalence of Emergent de Sitter Spaces from Conformal Field Theory

Curtis T. Asplund, Nele Callebaut, Claire Zukowski

Recently, two groups have made distinct proposals for a de Sitter space that is emergent from conformal field theory (CFT). The first proposal is that, for two-dimensional holograp…

Tunneling from a Minkowski vacuum to an AdS vacuum: A new thin-wall regime

Ali Masoumi, Sonia Paban, Erick J. Weinberg

Using numerical and analytic methods, we study quantum tunneling from a Minkowski false vacuum to an anti-de Sitter true vacuum. Scanning the parameter space of theories with quart…

A new 6d fixed point from holography

Fabio Apruzzi, Giuseppe Dibitetto, Luigi Tizzano

We propose a stringy construction giving rise to a class of interacting and non-supersymmetric CFT's in six dimensions. Such theories may be obtained as an IR conformal fixed point…

Disordered Quivers and Cold Horizons

Dionysios Anninos, Tarek Anous, Frederik Denef

We analyze the low temperature structure of a supersymmetric quiver quantum mechanics with randomized superpotential coefficients, treating them as quenched disorder. These theorie…

UV Completions for Non-Critical Strings

Fabio Apruzzi, Falk Hassler, Jonathan J. Heckman +1

Compactifications of the physical superstring to two dimensions provide a general template for realizing 2D conformal field theories coupled to worldsheet gravity, i.e. non-critica…

6D RG Flows and Nilpotent Hierarchies

Jonathan J. Heckman, Tom Rudelius, Alessandro Tomasiello

With the eventual aim of classifying renormalization group flows between 6D superconformal field theories (SCFTs), we study flows generated by the vevs of "conformal matter," a gen…
