The moduli space of complex Lagrangian submanifolds
Published 1999“…Following an earlier paper on the differential-geometric structure of the moduli space of special Lagrangian submanifolds in a Calabi-Yau manifold, we follow an analogous approach for compact complex Lagrangian submanifolds of a (K\"ahlerian) complex symplectic manifold. …”

The Atiyah class and complex structure stabilization in heterotic Calabi-Yau compactifications
Published 2011“…Holomorphic gauge fields in N = 1 supersymmetric heterotic compactifications can constrain the complex structure moduli of a Calabi-Yau manifold. In this paper, the tools necessary to use holomorphic bundles as a mechanism for moduli stabilization are systematically developed. …”

Matter field Kahler metric in heterotic string theory from localisation
Published 2018“…In a final step, we show how this local result can be expressed in terms of the global moduli of the Calabi-Yau manifold. The method is illustrated for the family of Calabi-Yau hypersurfaces embedded in ℙ1× ℙ3and we obtain an explicit result for the matter field Kähler metric in this case.…”

The exceptional holonomy groups and calibrated geometry
Published 2004“…There are also more complicated constructions which begin with a Calabi-Yau manifold or orbifold. Part II discusses the calibrated submanifolds of G2 and Spin(7)-manifolds: associative 3-folds and coassociative 4-folds for G2, and Cayley 4-folds for Spin(7). …”

The origin of Calabi-Yau crystals in BPS states counting
Published 2024-03-01“…Abstract We study the counting problem of BPS D-branes wrapping holomorphic cycles of a general toric Calabi-Yau manifold. We evaluate the Jeffrey-Kirwan residues for the flavoured Witten index for the supersymmetric quiver quantum mechanics on the worldvolume of the D-branes, and find that BPS degeneracies are described by a statistical mechanical model of crystal melting. …”

On the moduli space curvature at infinity
Published 2024-02-01“…Abstract We analyse the scalar curvature of the vector multiplet moduli space M X VM $$ {\mathcal{M}}_X^{\textrm{VM}} $$ of type IIA string theory compactified on a Calabi-Yau manifold X. While the volume of M X VM $$ {\mathcal{M}}_X^{\textrm{VM}} $$ is known to be finite, cases have been found where the scalar curvature diverges positively along trajectories of infinite distance. …”

Cutting the traintracks: Cauchy, Schubert and Calabi-Yau
Published 2023-04-01“…For L-loop full traintracks, we compute their leading singularities as integrals of (L−1)-forms, which proves that the rigidity is L−1 as expected; the form is given by an inverse square root of an irreducible polynomial quartic with respect to each variable, which characterizes an (L−1)-dim Calabi-Yau manifold (elliptic curve, K3 surface, etc.) for any L. …”
