The Simplicity of Perfect Atoms: Degeneracies in Supersymmetric Hydrogen

Tomas Rube, Jay G. Wacker

Supersymmetric QED hydrogen-like bound states are remarkably similar to non-supersymmetric hydrogen, including an accidental degeneracy of the fine structure and which is broken by…

Compactification Effects in D-brane Inflation

Daniel Baumann, Anatoly Dymarsky, Shamit Kachru +2

We determine the scalar potential for a D3-brane in a warped conifold background subject to general ultraviolet perturbations. Incorporating the effects of imaginary anti-self-dual…

Observations on Arithmetic Invariants and U-Duality Orbits in N =8 Supergravity

Massimo Bianchi, Sergio Ferrara, Renata Kallosh

We establish a relation between time-like, light-like and space-like orbits of the non-compact E{7(7)}(R)symmetry and discrete E{7(7)}(Z) invariants. We discuss the U-duality invar…

Conformality or confinement (II): One-flavor CFTs and mixed-representation QCD

Erich Poppitz, Mithat Unsal

We study QCD-like four dimensional theories in the theoretically controlled framework of deformation theory and/or twisted partition function on S*1 x R*3. By using duality, we sho…

R^4 counterterm and E7(7) symmetry in maximal supergravity

J. Broedel, L. J. Dixon

The coefficient of a potential R^4 counterterm in N=8 supergravity has been shown previously to vanish in an explicit three-loop calculation. The R^4 term respects N=8 supersymmetr…

A special road to AdS vacua

Davide Cassani, Sergio Ferrara, Alessio Marrani +2

We apply the techniques of special Kaehler geometry to investigate AdS_4 vacua of general N=2 gauged supergravities underlying flux compactifications of type II theories. We formul…
