The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; show every role.

We study the dynamics of D-branes in a smooth time-dependent background. The theory on the branes is a time-dependent non-commutative field theory. We find the metric and fluxes that determine the dual holographic closed string theory. This provides a concrete example of holography in a cosmological setting.

The paper

Original abstract

We study the dynamics of D-branes in a smooth time-dependent background. The theory on the branes is a time-dependent non-commutative field theory. We find the metric and fluxes that determine the dual holographic closed string theory. This provides a concrete example of holography in a cosmological setting.

Homogeneous Yang-Baxter deformations of the AdS5 x S5 string are Drinfeld twists of the symmetry algebra, and their gauge duals are conjectured to be twist-noncommutative N=4 SYM, with brane-construction support for t...

A one-loop calculation in the null-brane matrix model produces an attractive potential and strong particle production near the singularity, suggesting that spacetime dissolves into a gluon phase.
