A Landscape of Field Theories
Travis Maxfield, Daniel Robbins, Savdeep Sethi
Studying a quantum field theory involves a choice of space-time manifold and a choice of background for any global symmetries of the theory. We argue that many more choices are pos…
The alpha'-Expansion of Calabi-Yau Compactifications
Katrin Becker, Melanie Becker, Daniel Robbins
We consider alpha'-corrections to Calabi-Yau compactifications of type II string theory. These were discussed from the string worldsheet approach many years ago in terms of supersy…
Scalar-Vector Bootstrap
Fernando Rejon-Barrera, Daniel Robbins
We work out all of the details required for implementation of the conformal bootstrap program applied to the four-point function of two scalars and two vectors in an abstract confo…
M-theory and G_2 Manifolds
Katrin Becker, Melanie Becker, Daniel Robbins
In this talk we report on recent progress in describing compactifications of string theory and M-theory on G_2 and Spin(7) manifolds. We include the infinite set of alpha'-correcti…
Some tree-level string amplitudes in the NSR formalism
Katrin Becker, Melanie Becker, Ilarion V. Melnikov +2
We calculate tree level scattering amplitudes for open strings using the NSR formalism. We present a streamlined symmetry-based and pedagogical approach to the computations, which…
String Corrected Spacetimes and SU(N)-Structure Manifolds
Katrin Becker, Melanie Becker, Daniel Robbins
Using an effective field theory approach and the language of SU(N)-structures, we study higher derivative corrections to the supersymmetry constraints for compactifications of stri…
