Vacuum String Field Theory
Leonardo Rastelli, Ashoke Sen, Barton Zwiebach
This is a brief review of vacuum string field theory, a new approach to open string field theory based on the stable vacuum of the tachyon. We discuss the sliver state explaining i…
Trimming the Tachyon String Field with SU(1,1)
Barton Zwiebach
A discrete symmetry of the string field tachyon condensate noted by Hata and Shinohara is identified as a discrete subgroup of an SU(1,1) symmetry acting on the ghost coordinates.…
Uncovering Infinite Symmetries on [p,q] 7-branes: Kac-Moody Algebras and Beyond
Oliver DeWolfe, Tamas Hauer, Amer Iqbal +1
In a previous paper we explored how conjugacy classes of the modular group classify the symmetry algebras that arise on type IIB [p,q] 7-branes. The Kodaira list of finite Lie alge…
Uncovering the Symmetries on [p,q] 7-branes: Beyond the Kodaira Classification
Oliver DeWolfe, Tamas Hauer, Amer Iqbal +1
We begin a classification of the symmetry algebras arising on configurations of type IIB [p,q] 7-branes. These include not just the Kodaira symmetries that occur when branes coales…
The Plumbing of Minimal Area Metrics
Michael Wolf, Barton Zwiebach
We study the metric of minimal area on a punctured Riemann surface under the condition that all nontrivial homotopy closed curves be longer than or equal to . By constructing d…
