D-Sitter Space: Causal Structure, Thermodynamics, and Entropy
Michal Fabinger, Eva Silverstein
We study the entropy of concrete de Sitter flux compactifications and deformations of them containing D-brane domain walls. We determine the relevant causal and thermodynamic prope…
Stringy Resolutions of Null Singularities
Michal Fabinger, Simeon Hellerman
We study string theory in supersymmetric time-dependent backgrounds. In the framework of general relativity, supersymmetry for spacetimes without flux implies the existence of a co…
On Smooth Time-Dependent Orbifolds and Null Singularities
Michal Fabinger, John McGreevy
We study string theory on a non-singular time-dependent orbifold of flat space, known as the `null-brane'. The orbifold group, which involves only space-like identifications, is ob…
Clean Time-Dependent String Backgrounds from Bubble Baths
O. Aharony, M. Fabinger, G. Horowitz +1
We consider the set of controlled time-dependent backgrounds of general relativity and string theory describing ``bubbles of nothing'', obtained via double analytic continuation of…
Higher-Dimensional Quantum Hall Effect in String Theory
Michal Fabinger
We construct a string theory realization of the 4+1d quantum Hall effect recently discovered by Zhang and Hu. The string theory picture contains coincident D4-branes forming an S^4…
Deconstructing Noncommutativity with a Giant Fuzzy Moose
Allan Adams, Michal Fabinger
We argue that the worldvolume theories of D-branes probing orbifolds with discrete torsion develop, in the large quiver limit, new non-commutative directions. This provides an expl…
