Anisotropic Extra Dimensions
Eleftherios Papantonopoulos, Antonios Papazoglou, Minas Tsoukalas
We consider the scenario where in a five-dimensional theory, the extra spatial dimension has different scaling than the other four dimensions. We find background maximally symmetri…
Black holes and stars in Horava-Lifshitz theory with projectability condition
Jared Greenwald, Antonios Papazoglou, Anzhong Wang
We systematically study spherically symmetric static spacetimes filled with a fluid in the Horava-Lifshitz theory of gravity with the projectability condition, but without the deta…
Strong coupling in extended Horava-Lifshitz gravity
Antonios Papazoglou, Thomas P. Sotiriou
An extension of Horava-Lifshitz gravity was recently proposed in order to address the pathological behavior of the scalar mode all previous versions of the theory exhibit. We show…
The consistency of codimension-2 braneworlds and their cosmology
Christos Charmousis, Georgios Kofinas, Antonios Papazoglou
We study axially symmetric codimension-2 cosmology for a distributional braneworld fueled by a localised 4D perfect fluid, in a 6D Lovelock theory. We argue that only the matching…
Properties of codimension-2 braneworlds in six-dimensional Lovelock theory
Christos Charmousis, Antonios Papazoglou
We consider maximally symmetric 3-branes embedded in a six-dimensional bulk spacetime with Lovelock dynamics. We study the properties of the solutions with respect to their induced…
Codimension-2 brane inflation
Hyun Min Lee, Antonios Papazoglou
We consider a probe codimension-2 brane inflation scenario in a warped six-dimensional flux compactification. Our background model is Salam-Sezgin gauged supergravity with codimens…
