Defect Branes
E. Bergshoeff, T. Ortin, F. Riccioni
We discuss some general properties of "defect branes", i.e. branes of co-dimension two, in (toroidally compactified) IIA/IIB string theory. In particular, we give a full classifica…
The D-brane U-scan
Eric A. Bergshoeff, Fabio Riccioni
We consider the D-branes that occur in IIA/IIB string theory compactified on a torus. We review how a general expression for the Wess-Zumino term of such branes is derived. We also…
A spin-4 analog of 3D massive gravity
Eric A. Bergshoeff, Marija Kovacevic, Jan Rosseel +2
A 6th-order, but ghost-free, gauge-invariant action is found for a 4th-rank symmetric tensor potential in a three-dimensional (3D) Minkowski spacetime. It propagates two massive mo…
Branes and wrapping rules
Eric A. Bergshoeff, Fabio Riccioni
We show that the branes of ten-dimensional IIA/IIB string theory must satisfy, upon toroidal compactification, specific wrapping rules in order to reproduce the number of supersymm…
Off-shell D=5, N=2 Riemann Squared Supergravity
Eric A. Bergshoeff, Jan Rosseel, Ergin Sezgin
We construct a new off-shell invariant in N=2, D=5 supergravity whose leading term is the square of the Riemann tensor. It contains a gravitational Chern-Simons term involving the…
A Non-relativistic Logarithmic Conformal Field Theory from a Holographic Point of View
Eric A. Bergshoeff, Sjoerd de Haan, Wout Merbis +1
We study a fourth-order derivative scalar field configuration in a fixed Lifshitz background. Using an auxiliary field we rewrite the equations of motion as two coupled second orde…
Dual doubled geometry
Eric A. Bergshoeff, Fabio Riccioni
We probe doubled geometry with dual fundamental branes, i.e. solitons. Restricting ourselves first to solitonic branes with more than two transverse directions we find that the dou…
Modes of Log Gravity
Eric A. Bergshoeff, Olaf Hohm, Jan Rosseel +1
The physical modes of a recently proposed D-dimensional "critical gravity", linearized about its anti-de Sitter vacuum, are investigated. All "log mode" solutions, which we categor…
String Solitons and T-duality
Eric A. Bergshoeff, Fabio Riccioni
We construct for arbitrary dimensions a universal T-duality covariant expression for the Wess-Zumino terms of supersymmetric String Solitons in toroidally compactified string theor…
