Bubbling Calabi-Yau geometry from matrix models
Nick Halmagyi, Takuya Okuda
We study bubbling geometry in topological string theory. Specifically, we analyse Chern-Simons theory on both the 3-sphere and lens spaces in the presence of a Wilson loop insertio…
Instantons, Hypermultiplets and the Heterotic String
Nick Halmagyi, Ilarion V. Melnikov, Savdeep Sethi
Hypermultiplet couplings in type IIA string theory on a Calabi-Yau space can be quantum corrected by D2-brane instantons wrapping special Lagrangian cycles. On the other hand, hype…
Penrose Limits of RG Fixed Points and PP-Waves with Background Fluxes
Richard Corrado, Nick Halmagyi, Kristian D. Kennaway +1
We consider a family of pp-wave solutions of IIB supergravity. This family has a non-trivial, constant 5-form flux, and non-trivial, (light-cone) time-dependent RR and NS-NS 3-form…
