Graviton and Scalar Two-Point Functions in a CDL Background for General Dimensions

Daniel S. Park

We compute the two-point functions of the scalar and graviton in a Coleman-De Luccia type instanton background in general dimensions. These are analytically continued to Lorentzian…

1/N Effects in Non-Relativistic Gauge-Gravity Duality

Allan Adams, Alexander Maloney, Aninda Sinha +1

We argue that higher-curvature terms in the gravitational Lagrangian lead, via non-relativistic gauge-gravity duality, to finite renormalization of the dynamical exponent of the du…

Dynamics and Stability of Light-Like Tachyon Condensation

Neil Barnaby, David J. Mulryne, Nelson J. Nunes +1

Recently, Hellerman and Schnabl considered the dynamics of unstable D-branes in the background of a linear dilaton. Remarkably, they were able to construct light-like tachyon solut…

Towards Realistic String Vacua From Branes At Singularities

Joseph P. Conlon, Anshuman Maharana, Fernando Quevedo

We report on progress towards constructing string models incorporating both realistic D-brane matter content and moduli stabilisation with dynamical low-scale supersymmetry breakin…

Energy Transfer in Multi Field Inflation and Cosmological Perturbations

Amjad Ashoorioon, Axel Krause, Krzysztof Turzynski

In cascade inflation and some other string inflation models, collisions of mobile branes with other branes or orbifold planes occur and lead to interesting cosmological signatures.…

Comments on Holographic Fermi Surfaces

Hsien-Hang Shieh, Greg van Anders

Recently, a mechanism for the development of a fermi surface in a holographic model of large N QCD with a baryon chemical potential was proposed. We examine similar constructions t…
