Critical String Vacua from Noncritical Manifolds: A Novel Framework for String Compactification | | Rolf Schimmrigk
; | | Date: |
12 Oct 1992 | | Journal: | Phys.Rev.Lett. 70 (1993) 3688-3691 | | Subject: | hep-th | | Abstract: | A new framework is found for the compactification of supersymmetric string theory. It is shown that the massless spectra of Calabi--Yau manifolds of complex dimension $D_{crit}$ can be derived from noncritical manifolds of complex dimension $2k + D_{crit}$, $kgeq 1$. These higher dimensional manifolds are spaces whose nonzero Ricci curvature is quantized in a particular way. This class is more general than that of Calabi--Yau manifolds because it contains spaces which correspond to critical string vacua with no Kähler deformations, i.e. no antigenerations, thus providing mirrors of rigid Calabi--Yau manifolds. The constructions introduced here lead to new insights into the relation between exactly solvable models and their mean field theories on the one hand and Calabi--Yau manifolds on the other. They also raise fundamental questions about the Kaluza--Klein concept of string compactification, in particular regarding the rôle played by the dimension of the internal theories. | | Source: | arXiv, hep-th/9210062 | | Services: | Forum | Review | PDF | Favorites | |
