Phantom and quantum matter in an Anti-de Sitter Universe

We consider an Anti-de Sitter Universe filled by quantum CFT with classical phantom matter and perfect fluid. The model represents the combination of a trace-anomaly annihilated and a phantom driven Anti-de Sitter Universes. The influence exerted by the quantum effects and phantom matter on the AdS space is discussed. Different energy conditions in this type of Universe are investigated and compared with those for the corresponding model in a de Sitter Universe.

Spontaneous Symmetry Breaking in the Brane-World

A simplified Randall-Sundrum-like model in 6 dimensions is discussed. The extra two dimensions correspond to the cone. The effective four-dimensional scalar self-interacting theory is studied at one-loop level. The contributions due to 6-dimensional parameters in four-dimensional beta-functions appear. Using such beta-functions the one-loop effective potential is calculated. The possibility of spontaneous symmetry breaking due to extra dimensions is demonstrated.
