Renormalized AdS action and Critical Gravity
Olivera Miskovic, Rodrigo Olea, Minas Tsoukalas
It is shown that the renormalized action for AdS gravity in even spacetime dimensions is equivalent -on shell- to a polynomial of the Weyl tensor, whose first non-vanishing term is…
Generalised Scale Invariant Theories
Antonio Padilla, David Stefanyszyn, Minas Tsoukalas
We present the most general actions of a single scalar field and two scalar fields coupled to gravity, consistent with second order field equations in four dimensions, possessing l…
Massive Gravity with Anisotropic Scaling
Bertha Cuadros-Melgar, Eleftherios Papantonopoulos, Minas Tsoukalas +1
We study a massive gravity theory which is Lorentz violating all the way from ultraviolet to infrared energy scales. At short distances the theory breaks diffeomorphism invariance…
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…
Perturbations of Gauss-Bonnet Black Strings in Codimension-2 Braneworlds
Bertha Cuadros-Melgar, Eleftherios Papantonopoulos, Minas Tsoukalas +1
We derive the Lichnerowicz equation in the presence of the Gauss-Bonnet term. Using the modified Lichnerowicz equation we study the metric perturbations of Gauss-Bonnet black strin…
Black Hole Solutions in 5D Horava-Lifshitz Gravity
G. Koutsoumbas, E. Papantonopoulos, P. Pasipoularides +1
We study the full spectrum of spherically symmetric solutions in the five dimensional non-projectable Horava-Lifshitz type gravity theories. For appropriate ranges of the coupling…
