Non-perturbative RR Potentials in the c=1 Matrix Model
David J. Gross, Johannes Walcher
We use the \hat c=1 matrix model to compute the potential energy V(C) for (the zero mode of) the RR scalar in two-dimensional type 0B string theory. The potential is induced by tur…
Dibaryons from Exceptional Collections
Christopher P. Herzog, Johannes Walcher
We discuss aspects of the dictionary between brane configurations in del Pezzo geometries and dibaryons in the dual superconformal quiver gauge theories. The basis of fractional br…
Comments on Supergravity Description of S-branes
Alex Buchel, Johannes Walcher
This is a note on the coupled supergravity-tachyon matter system, which has been earlier proposed as a candidate for the effective space-time description of S-branes. In particular…
Massless Flavor in Geometry and Matrix Models
Radu Roiban, Radu Tatar, Johannes Walcher
The proper inclusion of flavor in the Dijkgraaf-Vafa proposal for the solution of N=1 gauge theories through matrix models has been subject of debate in the recent literature. We h…
On Duality Walls in String Theory
Amihay Hanany, Johannes Walcher
Following the RG flow of an N=1 quiver gauge theory and applying Seiberg duality whenever necessary defines a duality cascade, that in simple cases has been understood holographica…
