Observations on the Space of Four Dimensional String and theory Vacua
Bobby S Acharya
The space of four dimensional string and theory vacua with non-Abelian gauge symmetry, chiral fermions and unbroken supersymmetry beyond the electroweak scale appears to be a d…
Freund-Rubin Revisited
B. S. Acharya, F. Denef, C. Hofman +1
We utilise the duality between M theory and Type IIA string theory to show the existence of Freund-Rubin compactifications of M theory on 7-manifolds with singularities supporting…
Compactification with Flux and Yukawa Hierarchies
B. S. Acharya
Flux compactifications of theory on certain -manifolds have vacua in which all moduli are determined.These vacua have discrete parameters - the flux quanta. Small changes…
Orientifolds, Mirror Symmetry and Superpotentials
Bobby Acharya, Mina Aganagic, Kentaro Hori +1
We consider orientifolds of Calabi-Yau 3-folds in the context of Type IIA and Type IIB superstrings. We show how mirror symmetry can be used to sum up worldsheet instanton contribu…
Chiral Fermions from Manifolds of Holonomy
Bobby Acharya, Edward Witten
M-theory compactification on a manifold X of holonomy can give chiral fermions in four dimensions only if X is singular. A number of examples of conical singularities that gi…
On Domain Walls of N=1 Supersymmetric Yang-Mills in Four Dimensions
Bobby Acharya, Cumrun Vafa
We study the BPS domain walls of supersymmetric Yang-Mills for arbitrary gauge group. We describe the degeneracies of domain walls interpolating between arbitrary pairs of vacua. A…
