Future Foam
Raphael Bousso, Ben Freivogel, Yasuhiro Sekino +4
We study pocket universes which have zero cosmological constant and non-trivial boundary topology. These arise from bubble collisions in eternal inflation. Using a simplified dust…
Viscosity Bound and Causality Violation
Mauro Brigante, Hong Liu, Robert C. Myers +2
In recent work we showed that, for a class of conformal field theories (CFT) with Gauss-Bonnet gravity dual, the shear viscosity to entropy density ratio, , could violate the…
Volume Weighted Measures of Eternal Inflation in the Bousso-Polchinski Landscape
Timothy Clifton, Stephen Shenker, Navin Sivanandam
We consider the cosmological dynamics associated with volume weighted measures of eternal inflation, in the Bousso-Polchinski model of the string theory landscape. We find that thi…
D-Brane Instability as a Large N Phase Transition
Lukasz Fidkowski, Stephen Shenker
In AdS/CFT analyticity suggests that certain singular behaviors expected at large 't Hooft coupling should continue smoothly to weak 't Hooft coupling where the gauge theory is tra…
Another Length Scale in String Theory?
Stephen H. Shenker
We suggest that some of the remarkable results on stringy dynamics which have been found recently indicate the existence of another dynamical length scale in string theory that, at…
