It is well known that there are a great many apparently consistent vacua of string theory. We draw attention to the fact that there appear to be very few Calabi--Yau manifolds with the Hodge numbers h^{11} and h^{21} both small. Of these, the case (h^{11}, h^{21})=(3,3) corresponds to a manifold on which a three generation heterotic model has recently been constructed. We point out also that there is a very close relation between this manifold and several familiar manifolds including the `three…

Calabi-Yau threefolds and heterotic string compactification
This thesis is concerned with Calabi-Yau threefolds and vector bundles upon them, which are the basic mathematical objects at the centre of smooth supersymmetric compactifications of heterotic string

Heterotic string models on smooth Calabi-Yau threefolds
This thesis contributes with a number of topics to the subject of string compactifications. In the first half of the work, I discuss the Hodge plot of Calabi-Yau threefolds realised as hypersurfaces
New Calabi‐Yau manifolds with small Hodge numbers
It is known that many Calabi‐Yau manifolds form a connected web. The question of whether all Calabi‐Yau manifolds form a single web depends on the degree of singularity that is permitted for the
Heterotic Models from Vector Bundles on Toric
We systematically approach the construction of heterotic E8 E8 Calabi-Yau models, based on compact Calabi-Yau three-folds arising from toric geometry and vector bundles on these manifolds. We focus
A three‐generation Calabi‐Yau manifold with small Hodge numbers
We present a complete intersection Calabi‐Yau manifold Y that has Euler number ‐72 and which admits free actions by two groups of automorphisms of order 12. These are the cyclic group ℤ12 and the
Yukawa textures from heterotic stability walls
A holomorphic vector bundle on a Calabi-Yau threefold, X, with h1,1(X) ≥ 2 can have regions of its Kähler cone where it is slope-stable, that is, where the four-dimensional theory is $ \mathcal{N} =
Heterotic models from vector bundles on toric Calabi-Yau manifolds
We systematically approach the construction of heterotic E8 × E8 Calabi-Yau models, based on compact Calabi-Yau three-folds arising from toric geometry and vector bundles on these manifolds. We focus

Mirror Symmetry of Minimal Calabi-Yau Manifolds
We perform the mirror transformations of Calabi-Yau manifolds with one moduli whose Hodge numbers $(h^{11}, h^{21})$ are minimally small. Since the difference of Hodge numbers is the generation of


Landau-Ginzburg String Vacua
Calabi‐Yau Manifolds: A Bestiary for Physicists
Calabi-Yau spaces are complex spaces with a vanishing first Chern class, or equivalently, with trivial canonical bundle (canonical class). They are used to construct possibly realistic (super)string
Construction of Calabi-yau 3-folds in P 6
We announce here the construction of examples of smooth Cala bi-Yau 3-folds inP6 of low degree, up to degree 17. In the last degree their constr uction is rather complicated, and parametrized by
Towards the Standard Model spectrum from elliptic Calabi-Yau
We show that it is possible to construct supersymmetric three-generation models of Standard Model gauge group in the framework of non-simply-connected elliptically fibered Calabi-Yau, without section
Finding the Mirror of the Beauville Manifold
We construct the mirror of the Beauville manifold. The Beauville manifold is a Calabi-Yau manifold with non-abelian fundamental group. We use the conjecture of Batyrev and Borisov to find the

The Pfaffian Calabi–Yau, its Mirror, and their Link to the Grassmannian G(2,7)
The rank 4 locus of a general skew-symmetric 7 × 7 matrix gives the Pfaffian variety in P20 which is not defined as a complete intersection. Intersecting this with a general P6 gives a Calabi–Yau
