The Weight of Little Strings: T-duality and Hasse Diagrams
Hamza Ahmed, Florent Baume, Paul-Konstantin Oehlmann
We study the worldvolume theories of stacks of heterotic NS5-branes probing a transverse singularity . We revisit and extend the original clas…
A Heterotic Kähler Gravity and the Distance Conjecture
Javier José Murgas Ibarra, Paul-Konstantin Oehlmann, Fabian Ruehle +1
Deformations of the heterotic superpotential give rise to a topological holomorphic theory with similarities to both Kodaira-Spencer gravity and holomorphic Chern-Simons theory. Al…
A Twist on Heterotic Little String Duality
Hamza Ahmed, Paul-Konstantin Oehlmann, Fabian Ruehle
In this work, we significantly expand the web of T-dualities among heterotic NS5-brane theories with eight supercharges. This is achieved by introducing twists involving outer auto…
Bounds and Dualities of Type II Little String Theories
Florent Baume, Paul-Konstantin Oehlmann, Fabian Ruehle
We explore the symmetry structure of Type II Little String Theories and their T-dualities. We construct these theories both from the bottom-up perspective starting with seed Superc…
