Toward the Gravity Dual of Heterotic Small Instantons
Fang Chen, Keshav Dasgupta, Paul Franche +1
The question of what happens when the heterotic SO(32) instanton becomes small was answered sometime back by Witten. The heterotic theory develops an enhanced Sp(2k) gauge symmetry…
Supersymmetric Configurations, Geometric Transitions and New Non-Kahler Manifolds
Fang Chen, Keshav Dasgupta, Paul Franche +2
We give a detailed derivation of a supersymmetric configuration of wrapped D5-branes on a two-cycle of a warped resolved conifold. Our analysis reveals that the resolved conifold s…
Initial Conditions for Non-Canonical Inflation
Paul Franche, Rhiannon Gwyn, Bret Underwood +1
We investigate the dynamics of homogeneous phase space for single-field models of inflation. Inflationary trajectories are formally attractors in phase space, but since in practice…
