$tring Theory and an Accelerating Universe
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
An accelerating Universe can be accommodated naturally within non-critical string theory, in which scattering is described by a superscattering matrix $ that does not factorize as…
A Liouville String Approach to Microscopic Time and Cosmology
J. Ellis, N. Mavromatos, D. Nanopoulos
In the non-critical string framework that we have proposed recently, the time is identified with a dynamical local renormalization group scale, the Liouville mode, and behaves…
A String Derivation of the $\nd{S}$ matrix
J Ellis, N E Mavromatos, D V Nanopoulos
We show that, in string theory, as a result of the -symmetries that preserve quantum coherence in the {\it full} string theory by coupling different mass levels, transi…
On the W-hair of String Black Holes and the Singularity Problem
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
We argue that the infinitely many gauge symmetries of string theory provide an infinite set of conserved (gauge) quantum numbers (W-hair) which characterise black hole states and m…
