The abstract, sentence by sentence

We study the leading quantum effects in the recently introduced Matrix Big Bang model. This amounts to a study of supersymmetric Yang-Mills theory compactified on the Milne orbifold. We find a one-loop potential that is attractive near the Big Bang. Surprisingly, the potential decays very rapidly at late times, where it appears to be generated by D-brane effects. Usually, general covariance constrains the form of any effective action generated by renormalization group flow. However, the form of our one-loop potential seems to violate these constraints in a manner that suggests a connection between the cosmological singularity and long wavelength, late time physics.

The paper

Original abstract

We study the leading quantum effects in the recently introduced Matrix Big Bang model. This amounts to a study of supersymmetric Yang-Mills theory compactified on the Milne orbifold. We find a one-loop potential that is attractive near the Big Bang. Surprisingly, the potential decays very rapidly at late times, where it appears to be generated by D-brane effects. Usually, general covariance constrains the form of any effective action generated by renormalization group flow. However, the form of our one-loop potential seems to violate these constraints in a manner that suggests a connection between the cosmological singularity and long wavelength, late time physics.

Supersymmetry Breaking by Fluxes
hep-th 2017-09 conditional novelty 6.0 of 10

Supersymmetry-breaking flux backgrounds in string theory are argued to be generically time-dependent rolling solutions rather than static vacua, which would invalidate standard de Sitter landscape constructions.
Forced Fluid Dynamics from Gravity
hep-th 2008-05 accept novelty 6.0 of 10

Regular asymptotically AdS5 solutions of the Einstein-dilaton system are shown to be dual to forced Navier-Stokes flows, with the stress tensor and Lagrangian computed to second order in derivatives.
Matrix String Description of Cosmic Singularities in a Class of Time-dependent Solutions
hep-th 2006-03 conditional novelty 6.0 of 10

A class of 1/2 BPS time-dependent supergravity solutions, including backgrounds with four-form flux, can be carried into weak-coupling matrix string theory, with three example families satisfying the decoupling conditions.
Matrix Model in a Class of Time Dependent Supersymmetric Backgrounds
hep-th 2006-03 conditional novelty 6.0 of 10

A matrix model for a class of time-dependent supersymmetric M-theory backgrounds is constructed by membrane regularization, and the action is argued to be exact to all orders in fermions, with fuzzy sphere solutions t...
Toward the End of Time
hep-th 2006-03 conditional novelty 6.0 of 10

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.
