Novel Ricci-Flat Ground States, Part 2
Ground states in superstring and other
theories with higher-dimensional spacetime are often describable by
compact Ricci-flat (Calabi-Yau) geometries. Extensive databases of such
well-studied varieties (almost half a billion of them!) exhibit a
"mirror symmetry," whereby half of such models are reflections of the
other half. In the last <2 years, this already vast collection has
been generalized to include zero-sets of Laurent polynomials encoded by
certain types of polytopes.
Since last year's report, the "small-distance" modifications required by the quantum nature of these models is now also understood and will be presented.
Refreshments will be served at 3:15pm
