Spherically symmetric solutions in modified Horava-Lifshitz gravity
Elias Kiritsis
We find spherically symmetric solutions in the modified Hořava-Lifshitz gravity proposed recently by Blas, Pujolas and Sibiryakov. The non-linear equations of the two derivative ac…
On Horava-Lifshitz "Black Holes"
Elias Kiritsis, Georgios Kofinas
The most general spherically symmetric solution with zero shift is found in the non-projectable Horava-Lifshitz class of theories with general coupling constants. It contains as sp…
SU(5) orientifolds, Yukawa couplings, Stringy Instantons and Proton Decay
Elias Kiritsis, Michael Lennek, Bert Schellekens
We construct a large class of SU(5) orientifold vacua with tadpole cancellation both for the standard and the flipped case. We give a general analysis of superpotential couplings u…
Thermal Transport and Drag Force in Improved Holographic QCD
Umut Gürsoy, Elias Kiritsis, Georgios Michalogiorgakis +1
We calculate the bulk viscosity, drag force and jet quenching parameter in Improved Holographic QCD. We find that the bulk viscosity rises near the phase transition but does not ex…
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…
Improved Holographic Yang-Mills at Finite Temperature: Comparison with Data
U. Gursoy, E. Kiritsis, L. Mazzanti +1
The semi-phenomenological improved holographic model for QCD is confronted with data of the pure glue, large-Nc gauge theory. After fitting two phenomenological parameters in the p…
