Eigenforms and special holonomy
Bobby Acharya, Lucía Cabrera, Simone Corbo +1
We prove existence and non-existence results for eigenforms for the Hodge Laplacian on complete non-compact Ricci flat manifolds with special holonomy, with a particular focu…
QCD String Axions and -theory
Bobby Samir Acharya, Ethan Torres
In Yang-Mills theory without matter, there exist stable long electric fluxtube strings which carry a 1-form symmetry charge. Over the past decade or so, there has been incr…
On Classifying HyperKähler Kummer 8-Orbifolds
Daniel Andrew Baldwin, Bobby Samir Acharya
HyperKähler spaces, including manifolds, orbifolds and conical singularities play an important role in superstring/-theory and gauge theories as well as in differential and alge…
Confinement in Five Dimensions
Bobby Samir Acharya
Five dimensional super conformal field theories can be studied using their geometric realisation as a limit of -theory on a metrically conical Calabi-Yau threefold. We utilise t…
Ricci Flat Metrics, Flat Connections and -Manifolds
Bobby Samir Acharya, Daniel Andrew Baldwin
Inspired by considerations in -theory, we prove the equivalence between the moduli spaces of (suitably complexified) torsion free -structures on 7-manifolds which are fam…
Coulomb and Higgs Phases of -manifolds
Bobby Samir Acharya, Daniel Andrew Baldwin
Ricci flat manifolds of special holonomy are a rich framework as models of the extra dimensions in string/-theory. At special points in vacuum moduli space, special kinds of sin…
