Non-linear sigma model in string field theory
Alexander Frenkel, Manki Kim
We revisit the non-linear sigma model approach to string theory with the closed superstring field theory. We construct the string field theory around the non-linear sigma model bac…

Not So Flat Metrics
Kit Fraser-Taliente, Thomas R. Harvey, Manki Kim
In order to be in control of the derivative expansion, geometric string compactifications are understood in the context of a large volume approximation. In this letter, we con…

String perturbation theory of Klebanov-Strassler throat
Manki Kim
In this work, we develop a tool to study string perturbation theory of the Klebanov-Strassler solution in the large radius approximation based on open-closed superstring field theo…
