Comments on the Holographic Picture of the Randall-Sundrum Model
R. Rattazzi, A. Zaffaroni
We discuss some issues about the holographic interpretation of the compact Randall-Sundrum model, which is conjectured to be dual to a 4d field theory with non-linearly realized co…
Hamiltonian structure and quantization of 2+1 dimensional gravity coupled to particles
Luigi Cantini, Pietro Menotti, Domenico Seminara
It is shown that the reduced particle dynamics of 2+1 dimensional gravity in the maximally slicing gauge has hamiltonian form. This is proved directly for the two body problem and…
Quantum delocalization of the electric charge
Detlev Buchholz, Sergio Doplicher, Giovanni Morchio +2
The classical Maxwell-Dirac and Maxwell-Klein-Gordon theories admit solutions of the field equations where the corresponding electric current vanishes in the causal complement of s…
Covariant Quantization of the Brink-Schwarz Superparticle
P. A. Grassi, G. Policastro, M. Porrati
The quantization of the Brink-Schwarz-Casalbuoni superparticle is performed in an explicitly covariant way using the antibracket formalism. Since an infinite number of ghost fields…
Statistical properties of classical gravitating particles in (2+1) dimensions
M. Ghilardi, E. Guadagnini
We report the statistical properties of classical particles in (2+1) gravity as resulting from numerical simulations. Only particle momenta have been taken into account. In the ran…
Localization of Quantum Fields on Branes
Mihail Mintchev, Luigi Pilo
A mechanism for localization of quantum fields on a -brane, representing the boundary of a s+2 dimensional bulk space, is investigated. Minkowski and AdS bulk spaces are analyze…
