$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…
M-Phenomenology
D. V. Nanopoulos
Recent developments involving strongly coupled superstrings are discussed from a phenomenological point of view. In particular, strongly coupled is described as an…
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…
Flipped SU(5): Origins and Recent Developments
J. Lopez, D. Nanopoulos
We present an account of the early developments that led to the present form of the flipped string model. We focus on the method used to decide on this particular string mo…
