Quantum (in)stability of maximally symmetric space-times
Jewel K. Ghosh, Elias Kiritsis, Francesco Nitti +1
Classical gravity coupled to a CFT (matter) is considered. The effect of the quantum dynamics of matter on gravity is studied around maximally symmetric spaces (flat, de Sitter…

Dynamical Topology Change, Compactification and Waves in String Cosmology
E. Kiritsis, C. Kounnas
Exact string solutions are presented, where moduli fields are varying with time. They provide examples where a dynamical change of the topology of space is occurring. Some other so…

String Gravity and Cosmology: Some new ideas
Elias Kiritsis, Costas Kounnas
String theory provides the only consistent framework so far that unifies all interactions including gravity. We discuss gravity and cosmology in string theory. Conventional notions…
