Entanglement entropy and the Ricci flow
Sergey N. Solodukhin
We analyze the Ricci flow of a noncompact metric that describes a two-dimensional black hole. We consider entanglement entropy of a 2d black hole which is due to the quantum correl…
Entanglement entropy of black holes and AdS/CFT correspondence
Sergey N. Solodukhin
A recent proposal by Ryu and Takayanagi for a holographic interpretation of entanglement entropy in conformal field theories dual to supergravity on anti-de Sitter (adS) is general…
Localising gravity in composite monopole brane worlds without bulk cosmological constant
Eugenio R. Bezerra de Mello, Betti Hartmann
We study a 7-dimensional brane world scenario with a Ricci-flat 3-brane residing in the core of a composite monopole defect, i.e. a defect composed of a 'tHooft-Polyakov and a glob…
Inflating branes inside abelian strings
Y. Brihaye, T. Delsate, B. Hartmann
We study a 6-dimensional brane world model with an abelian string residing in the two extra dimensions. We study both static as well as inflating branes and find analytic solutions…
