Abstract
By considering the effects of string winding and momentum modes ona time dependent background, we find a method by which six compactdimensions become stabilized naturally at the self-dual radiuswhile three dimensions grow large.
Highlights
String theory continues to be a promising candidate for a quantum theory of gravity
There are several key challenges in an attempt to relate the theory to phenomenology. One such issue is that string theory predicts a number of extra spatial dimensions
We will demonstrate that, working in the regime of weak string coupling and at tree level in α′, we find that the dynamics of string winding and momentum modes lead to a natural mechanism to stabilize the extra dimensions at the self-dual radius
Summary
String theory continues to be a promising candidate for a quantum theory of gravity. there are several key challenges in an attempt to relate the theory to phenomenology. The authors of [1] argued that, by considering the dynamics of the winding and momentum modes of the strings, a new symmetry specific of string theory, namely t-duality, could eliminate the big-bang singularity and explain the dimensionality of space-time. These result from demanding conformal invariance of the world-sheet action (vanishing β functions).
