Horava-Lifshitz Cosmology

Elias Kiritsis, Georgios Kofinas

The cosmological equations suggested by the non-relativistic renormalizable gravitational theory proposed by Hořava are considered. It is pointed out that the early universe cosmol…

On mass hierarchies in orientifold vacua

Pascal Anastasopoulos, Elias Kiritsis, Andrea Lionetto

We analyze the problem of the hierarchy of masses and mixings in orientifold realizations of the Standard Model. We find bottom-up brane configurations that can generate such hiera…

Dissecting the string theory dual of QCD

Elias Kiritsis

Input from QCD and string theory is used in order to elucidate basic features of the string theory dual of QCD, It is argued that the relevant string theory is a five-dimensional v…

Free Fermion Orientifolds

Elias Kiritsis, Michael Lennek, Bert Schellekens

We investigate a class of orientifold models based on tensor products of 18 Ising models. Using the same search criteria as for the comparable case of Gepner model orientifolds we…

Torsion and the Gravity Dual of Parity Symmetry Breaking in AdS4/CFT3 Holography

Robert G. Leigh, Nam N. Hoang, Anastasios C. Petkou

We study four dimensional gravity with a negative cosmological constant deformed by the Nieh-Yan torsional topological invariant with a spacetime-dependent coefficient. We find an…

Interacting String Multi-verses and Holographic Instabilities of Massive Gravity

Elias Kiritsis, Vasilis Niarchos

Products of large-N conformal field theories coupled by multi-trace interactions in diverse dimensions are used to define quantum multi-gravity (multi-string theory) on a union of…
