Holographic thermalization of mutual and tripartite information in 2d CFTs

Alice Bernamonti, Neil Copland, Ben Craps +1

We discuss the concepts of mutual and tripartite information by referring to simple intuitive examples, and describe their use as probes of thermalization in holographic models. We…

A note on obstinate tachyons in classical dS solutions

Ulf H. Danielsson, Gary Shiu, Thomas Van Riet +1

The stabilisation of the dilaton and volume in tree-level flux compactifications leads to model independent and thus very powerful existence and stability criteria for dS solutions…

The Chern-Simons Diffusion Rate in Improved Holographic QCD

Umut Gursoy, Ioannis Iatrakis, Elias Kiritsis +2

In (3+1)-dimensional SU(Nc) Yang-Mills (YM) theory, the Chern-Simons diffusion rate, Gamma_{CS}, is determined by the zero-momentum, zero-frequency limit of the retarded two-point…

Freudenthal Dual Lagrangians

L. Borsten, M. J. Duff, S. Ferrara +1

The global U-dualities of extended supergravity have played a central role in differentiating the distinct classes of extremal black hole solutions. When the U-duality group satisf…

IIB Duals of D=3 N=4 Circular Quivers

Benjamin Assel, Costas Bachas, John Estes +1

We construct the type-IIB supergravity solutions which are dual to the three-dimensional superconformal field theories that arise as infrared fixed poi…

An off-shell formulation for internally gauged D=5, N=2 supergravity from superconformal methods

Frederik Coomans, Mehmet Ozkan

We use the superconformal method to construct a new formulation for pure off-shell D=5, N=2 Poincaré supergravity and present its internal gauging. The main difference between the…

Holographic Wilson Loops, Dielectric Interfaces, and Topological Insulators

John Estes, Andy O'Bannon, Efstratios Tsatis +1

We use holography to study (3+1)-dimensional N=4 supersymmetric SU(Nc) Yang-Mills theory (SYM) in the large-Nc and large coupling limits, with a (2+1)-dimensional interface where t…

Exact Half-BPS Flux Solutions in M-theory with Symmetry: Local Solutions

John Estes, Roman Feldman, Darya Krym

We construct local solutions to 11-dimensional supergravity (or M-theory), which are invariant under the superalgebra for all values of the pa…

Conjecture on Hidden Superconformal Symmetry of N=4 Supergravity

Sergio Ferrara, Renata Kallosh, Antoine Van Proeyen

We argue that the observed UV finiteness of the 3-loop extended supergravities may be a manifestation of a hidden local superconformal symmetry of supergravity. We focus on the SU(…

All homogeneous N=2 M-theory truncations with supersymmetric AdS4 vacua

Davide Cassani, Paul Koerber, Oscar Varela

We study consistent truncations of M-theory to gauged N=2 supergravity in four dimensions, based on a large class of SU(3)-structures in seven dimensions. We show that the gauging…

The Wave Function of Vasiliev's Universe - A Few Slices Thereof

Dionysios Anninos, Frederik Denef, Daniel Harlow

We study the partition function of the free Sp(N) conformal field theory recently conjectured to be dual to asymptotically de Sitter higher-spin gravity in four-dimensions. We comp…

Quantum Probabilities for Inflation from Holography

James B. Hartle, S. W. Hawking, Thomas Hertog

The evolution of the universe is determined by its quantum state. The wave function of the universe obeys the constraints of general relativity and in particular the Wheeler-DeWitt…

Large N Free Energy of 3d N=4 SCFTs and AdS/CFT

Benjamin Assel, John Estes, Masahito Yamazaki

We provide a non-trivial check of the AdS_4/CFT_3 correspondence recently proposed in arXiv:1106.4253 by verifying the GKPW relation in the large N limit. The CFT free energy is ob…

Supergoop Dynamics

Dionysios Anninos, Tarek Anous, Frederik Denef +2

We initiate a systematic study of the dynamics of multi-particle systems with supersymmetric Van der Waals and electron-monopole type interactions. The static interaction allows a…

Black hole solutions to the -model and their orbits (I)

W. Chemissany, P. Giaccone, D. Ruggeri +1

In this paper we continue the program of the classification of nilpotent orbits using the approach developed in arXiv:1107.5986, within the study of black hole solutions in D=4 sup…

Affine Quantization and the Initial Cosmological Singularity

Michaël Fanuel, Simone Zonetti

The Affine Coherent State Quantization procedure is applied to the case of a FRLW universe in the presence of a cosmological constant. The quantum corrections alter the dynamics of…

Higher Derivative Extension of 6D Chiral Gauged Supergravity

Eric Bergshoeff, Frederik Coomans, Ergin Sezgin +1

Six-dimensional (1,0) supersymmetric gauged Einstein-Maxwell supergravity is extended by the inclusion of a supersymmetric Riemann tensor squared invariant. Both the original model…

Towards the field theory of the Standard Model on fractional D6-branes on T6/Z6': Yukawa couplings and masses

Gabriele Honecker, Joris Vanhoof

We present the perturbative Yukawa couplings of the Standard Model on fractional intersecting D6-branes on T6/Z6' and discuss two mechanisms of creating mass terms for the vector-l…
