Taming the Landscape of Effective Theories

Thomas W. Grimm

We introduce a generalized notion of finiteness that provides a structural principle for the set of effective theories that can be consistently coupled to quantum gravity. More con…

Analytic long-lived modes in charged critical plasma

Umut Gursoy, Matti Järvinen, Giuseppe Policastro +1

Fluctuations around critical behavior of a holographic charged plasmas are investigated by studying quasi-normal modes of the corresponding black branes in 5D Einstein-Maxwell-Dila…

Moduli Stabilization in Asymptotic Flux Compactifications

Thomas W. Grimm, Erik Plauschinn, Damian van de Heisteeg

We present a novel strategy to systematically study complex-structure moduli stabilization in Type IIB and F-theory flux compactifications. In particular, we determine vacua in any…

Deformed WZW Models and Hodge Theory -- Part I

Thomas W. Grimm, Jeroen Monnee

We investigate a relationship between a particular class of two-dimensional integrable non-linear -models and variations of Hodge structures. Concretely, our aim is to study the…

Building spacetime from effective interactions between quantum fluctuations

Anna Karlsson

We describe how a model of effective interactions between quantum fluctuations under certain assumptions can be constructed in a way so that the large-scale limit gives an effectiv…

The tadpole conjecture at large complex-structure

Erik Plauschinn

The tadpole conjecture by Bena, Blaback, Grana and Lust effectively states that for string-theory compactifications with a large number of complex-structure moduli, not all of thes…

scattering: Eikonalisation and the Page curve

Nava Gaddam, Nico Groenenboom

In the spirit of studying the information paradox as a scattering problem, we pose and answer the following questions: i) What is the scattering amplitude for particles to emer…

Analytic Periods via Twisted Symmetric Squares

Rafael Álvarez-García, Lorenz Schlechter

We study the symmetric square of Picard-Fuchs operators of genus one curves and the thereby induced generalized Clausen identities. This allows the computation of analytic expressi…

M2-branes on Discs and Multi-Charged Spindles

Christopher Couzens, Koen Stemerdink, Damian van de Heisteeg

We study supersymmetric AdS solutions of 11d supergravity where is an fibration over a Riemann surface equipped with a metric of non-constant curvature. W…

Thermodynamics and transport of holographic nodal line semimetals

Ronnie Rodgers, Enea Mauri, Umut Gürsoy +1

We study various thermodynamic and transport properties of a holographic model of a nodal line semimetal (NLSM) at finite temperature, including the quantum phase transition to a t…

N=(0,4) Black String Chains

Christopher Couzens, Yolanda Lozano, Nicolò Petri +1

We construct black string solutions in Type IIA supergravity arising from intersecting D2-D4-D6-NS5 branes in the presence of fractional D4-branes. The fractional D4-branes arise f…

AdS from D3-branes wrapped on Riemann surfaces

Christopher Couzens, Niall T. Macpherson, Achilleas Passias

We construct supersymmetric AdS solutions of type IIB supergravity, dual to twisted compactifications of 4d super-Yang--Mills on Riemann sur…

Holographic QCD and magnetic fields

Umut Gursoy

We review the holographic approach to electromagnetic phenomena in large N QCD. After a brief discussion of existing holographic models, we concentrate on the improved holographic…

A non-relativistic limit of M-theory and 11-dimensional membrane Newton-Cartan geometry

Chris D. A. Blair, Domingo Gallegos, Natale Zinnato

We consider a non-relativistic limit of the bosonic sector of eleven-dimensional supergravity, leading to a theory based on a covariant `membrane Newton-Cartan' (MNC) geometry. The…

Bulk Reconstruction in Moduli Space Holography

Thomas W. Grimm, Jeroen Monnee, Damian van de Heisteeg

It was recently suggested that certain UV-completable supersymmetric actions can be characterized by the solutions to an auxiliary non-linear sigma-model with special asymptotic bo…

Hydrodynamics of spin currents

Domingo Gallegos, Umut Gursoy, Amos Yarom

We study relativistic hydrodynamics in the presence of a non vanishing spin chemical potential. Using a variety of techniques we carry out an exhaustive analysis, and identify the…
