We study the conjectured connection between AdS bubbles (AdS solitons) and closed string
tachyon condensations. We confirm that the entanglement entropy, which measures the …

As an alternative to the standard Dirichlet counterterms prescription, I introduce the concept
of Kounterterms as the boundary terms with explicit dependence on the extrinsic curvature K …

A bstract We study the thermodynamics of an exact hairy black hole solution in Anti-deSitter
(AdS) spacetime. We use the counterterm method supplemented with boundary terms for the …

We investigate five-dimensional static (non-) extremal black hole solutions in higher
derivative Anti-de Sitter gravity theories with neutral scalars non-minimally coupled to gauge …

We present arguments for the existence of new black string solutions with negative
cosmological constant. These higher-dimensional configurations have no dependence on …

We construct new solutions of the vacuum Einstein field equations with multiple NUT
parameters, with and without cosmological constant. These solutions describe spacetimes …

This paper deals with black holes, bubbles and orbifolds in Gauss–Bonnet theory in five
dimensional anti de Sitter space. In particular, we study stable, unstable and metastable …

We first reconstruct the conserved (Abbott-Deser) charges in the spin-connection formalism
of gravity for asymptotically (Anti)-de Sitter spaces, and then compute the masses of the A d …

We generalize the vacuum static black string solutions of Einstein's equations with negative
cosmological constant recently discussed in literature, by including an electromagnetic field …

We study the phase structures of Script N= 4 U (N) super Yang-Mills theories on Bbb R× S
3/Bbb Z k with large N. The theory has many vacua labelled by the holonomy matrix along …
