Holomorphic supergravity in ten dimensions and anomaly cancellation
Anthony Ashmore, Javier José Murgas Ibarra, Charles Strickland-Constable +1
We formulate a ten-dimensional version of Kodaira-Spencer gravity on a Calabi-Yau five-fold that reproduces the classical Maurer-Cartan equation governing supersymmetric heterotic…
A heterotic Kodaira-Spencer theory at one-loop
Anthony Ashmore, Javier José Murgas Ibarra, David Duncan McNutt +4
We consider a heterotic version of six-dimensional Kodaira-Spencer gravity derived from the heterotic superpotential. We compute the one-loop partition function and find it can be…
Numerical spectra of the Laplacian for line bundles on Calabi-Yau hypersurfaces
Anthony Ashmore, Yang-Hui He, Elli Heyes +1
We give the first numerical calculation of the spectrum of the Laplacian acting on bundle-valued forms on a Calabi-Yau three-fold. Specifically, we show how to compute the approxim…
Calabi-Yau metrics, CFTs and random matrices
Anthony Ashmore
Calabi-Yau manifolds have played a key role in both mathematics and physics, and are particularly important for deriving realistic models of particle physics from string theory. Un…
Moduli-dependent KK towers and the swampland distance conjecture on the quintic Calabi-Yau manifold
Anthony Ashmore, Fabian Ruehle
We use numerical methods to obtain moduli-dependent Calabi-Yau metrics and from them the moduli-dependent massive tower of Kaluza-Klein states for the one-parameter family of quint…
Explicit Soft Supersymmetry Breaking in the Heterotic M-Theory MSSM
Anthony Ashmore, Sebastian Dumitru, Burt A. Ovrut
The strongly coupled heterotic M-theory vacuum for both the observable and hidden sectors of the MSSM theory is reviewed, including a discussion of the "bundle" constraints t…
