Fermionic and bosonic mass deformations of N=4 SYM and their bulk supergravity dual
Iosif Bena, Mariana Graña, Stanislav Kuperstein +2
We examine the AdS-CFT dual of arbitrary (non)supersymmetric fermionic mass deformations of N=4 SYM, and investigate how the backreaction of the RR and NS-NS two-form potentials du…
D3-brane model building and the supertrace rule
Iosif Bena, Mariana Graña, Stanislav Kuperstein +2
A common way to obtain standard-model-like Lagrangians in string theory is to place D3-branes inside flux compactifications. The bosonic and fermionic masses and couplings of the r…
Brane polarization is no cure for tachyons
Iosif Bena, Stanislav Kuperstein
Anti-M2 and anti-D3 branes placed in regions with charges dissolved in fluxes have a tachyon in their near-horizon region, which causes these branes to repel each other. If the bra…
A deformed conifold with a cosmological constant
Stanislav Kuperstein
We find a new regular solution of six-dimensional Einstein's equations with a positive cosmological constant. It has the same isometry group as the (deformed) conifold geometry, an…
Holography as a highly efficient RG flow I: Rephrasing gravity
Nicolas Behr, Stanislav Kuperstein, Ayan Mukhopadhyay
We investigate how the holographic correspondence can be reformulated as a generalisation of Wilsonian RG flow in a strongly interacting large quantum field theory. We firstly…
