Chaotic Cascades for D-branes on Singularities
Sebastian Franco, Yang-Hui He, Christopher Herzog +1
We briefly review our work on the cascading renormalization group flows for gauge theories on D-branes probing Calabi-Yau singularities. Such RG flows are sometimes chaotic and exh…
Discrete Torsion in Singular G_2-Manifolds and Real LG
Radu Roiban, Christian Romelsberger, Johannes Walcher
We investigate strings at singularities of G_2-holonomy manifolds which arise in Z_2 orbifolds of Calabi-Yau spaces times a circle. The singularities locally look like R^4/Z_2 fibe…
A new kind of McKay correspondence from non-Abelian gauge theories
W. Lerche, P. Mayr, J. Walcher
The boundary chiral ring of a 2d gauged linear sigma model on a Kähler manifold classifies the topological D-brane sectors and the massless open strings between them. While it…
