Euclidean axion wormholes have multiple negative modes
Thomas Hertog, Brecht Truijen, Thomas Van Riet
We show that Euclidean axion wormholes in theories of gravity coupled to a single axion have several independent inhomogeneous perturbations that lower the Euclidean action. Our an…
Holography, Brane Intersections and Six-dimensional SCFTs
Nikolay Bobev, Giuseppe Dibitetto, Fridrik Freyr Gautason +1
We study supersymmetric intersections of NS5-, D6- and D8-branes in type IIA string theory. We focus on the supergravity description of this system and identify a "near horizon" li…
Comments on fake supersymmetry
Juan Diaz Dorronsoro, Brecht Truijen, Thomas Van Riet
Flat domain walls and spherical black holes are solutions to coupled second-order ODE's of the Hamiltonian form. Hamilton-Jacobi theory then implies that first-order flow equations…
The many faces of brane-flux annihilation
Fridrik Freyr Gautason, Brecht Truijen, Thomas Van Riet
Fluxes can decay via the nucleation of Brown-Teitelboim bubbles, but when the decaying fluxes induce D-brane charges this process must be accompanied with an annihilation of D-bran…
Smeared antibranes polarise in AdS
Fridrik Freyr Gautason, Brecht Truijen, Thomas Van Riet
In the recent literature it has been questioned whether the local backreaction of antibranes in flux throats can induce a perturbative brane-flux decay. Most evidence for this can…
Non-SUSY fractional branes
Stanislav Kuperstein, Brecht Truijen, Thomas Van Riet
We consider a simplified Ansatz for supergravity solutions describing fractional p-brane solutions (throat geometries supported by fluxes) for various p. For p=3 the Ansatz capture…
