A (0,2) mirror duality
Abstract
We construct a class of exactly solved (0,2) heterotic compactifications,
similar to the (2,2) models constructed by Gepner. We identify these as special
points in moduli spaces containing geometric limits described by non-linear
sigma models on complete intersection Calabi-Yau spaces in toric varieties,
equipped with a bundle whose rank is strictly greater than that of the tangent
bundle. These moduli spaces do not in general contain a locus exhibiting (2,2)
supersymmetry. A quotient procedure at the exactly solved point realizes the
mirror isomorphism, as was the case for Gepner models. We find a geometric
interpretation of the mirror duality in the context of hybrid models.

My research is in String Theory, the most ambitious attempt yet at a comprehensive
theory of the fundamental structure of the universe. In some (rather imprecise) sense,
string theory replaces the particles that form the fundamental building blocks for
conventional theories (the fields, or wave phenomena, we observe are obtained starting
from particles when we apply the principles of quantum mechanics) with objects that
are not point-like but extended in one dimension – strings. At present, th
