Boundary Scattering in 1+1 Dimensions as an Aharanov-Bohm Effect
Surya Ganguli, Petr Horava, Anthony Ndirango
The boundary scattering problem in 1+1 dimensional CFT is relevant to a multitude of areas of physics, ranging from the Kondo effect in condensed matter theory to tachyon condensat…
E10 Orbifolds
Jeffrey Brown, Surya Ganguli, Ori J. Ganor +1
We study Z2 orbifolds of M-theory in terms of E10. We find a simple relation between the Z2 action on E10 and the imaginary root that corresponds [hep-th/0401053] to the "twisted s…
Twisted Six Dimensional Gauge Theories on Tori, Matrix Models, and Integrable Systems
Surya Ganguli, Ori J. Ganor, James A. Gill
We use the Dijkgraaf-Vafa technique to study massive vacua of 6D SU(N) SYM theories on tori with R-symmetry twists. One finds a matrix model living on the compactification torus wi…
Holographic Protection of Chronology in Universes of the Godel Type
Edward Boyda, Surya Ganguli, Petr Horava +1
We analyze the structure of supersymmetric Godel-like cosmological solutions of string theory. Just as the original four-dimensional Godel universe, these solutions represent rotat…
