Non-Abelian Giant Gravitons

Bert Janssen, Yolanda Lozano

We argue that the giant graviton configurations known from the literature have a complementary, microscopical description in terms of multiple gravitational waves undergoing a diel…

Comments on the classification of orientifolds

L. R. Huiszoon

The simple current construction of orientifolds based on rational conformal field theories is reviewed. When applied to SO(16) level 1, one can describe all ten-dimensional orienti…

Explicit factorization of Seiberg-Witten curves with matter from random matrix models

Yves Demasure, Romuald A. Janik

Within the Dijkgraaf-Vafa correspondence, we study the complete factorization of the Seiberg-Witten curve for U(N_c) gauge theory with N_f<N_c massive flavors. We obtain explicit e…

Solutions to the Massive HLW IIA Supergravity

Jos Gheerardyn

We find new supersymmetric solutions of the massive supergravity theory which can be constructed by generalized Scherk-Schwarz dimensional reduction of eleven dimensional supergrav…

Effective matter superpotentials from Wishart random matrices

Yves Demasure, Romuald A. Janik

We show how within the Dijkgraaf-Vafa prescription one can derive superpotentials for matter fields. The ingredients forming the non-perturbative Affleck-Dine-Seiberg superpotentia…

The Schwinger Model and the Physical Projector: a Nonperturbative Quantization without Gauge Fixing

Gabriel Y. H. Avossevou, Jan Govaerts

Based on the physical projector approach, a nonpertubative quantization of the massless Schwinger model is considered which does not require any gauge fixing. The spectrum of physi…

The Quantum Geometer's Universe: Particles, Interactions and Topology

Jan Govaerts

With the two most profound conceptual revolutions of XXth century physics, quantum mechanics and relativity, which have culminated into relativistic spacetime geometry and quantum…

Black holes on cylinders are not algebraically special

Pieter-Jan De Smet

We give a Petrov classification for five-dimensional metrics. We classify Ricci-flat metrics that are static, have an SO(3) isometry group and have Petrov type 22. We use this clas…

Superconformal N=2, D=5 matter with and without actions

Eric Bergshoeff, Sorin Cucu, Tim de Wit +4

We investigate N=2, D=5 supersymmetry and matter-coupled supergravity theories in a superconformal context. In a first stage we do not require the existence of a Lagrangian. Under…

Stable de Sitter Vacua from N=2 Supergravity

Pietro Fre, Mario Trigiante, Antoine Van Proeyen

We find extrema of the potential of matter couplings to N=2 supergravity that define de Sitter vacua and no tachyonic modes. There are three essential ingredients in our constructi…
