| Spacetime Emergence in the Robertson-Walker Universe from a Matrix model |
| Speaker: | Rene Meyer |
| Abstract: | Using a novel, string theory-inspired formalism based on a Hamiltonian
constraint, we obtain a conformal mechanical system for the spatially flat
four-dimensional Robertson-Walker universe. Depending on parameter
choices, this system describes either a relativistic particle in the
Robertson-Walker background, or metric fluctuations of the
Robertson-Walker geometry. On that basis we derive a tree-level matrix
model in this time-dependent background by comparing with 2-brane
dynamics. Imposing the Hamiltonian constraint of the matrix model forces
the spacetime geometry to be fuzzy near the cosmological singularity,
while the classical Robertson-Walker geometry emerges as the universe
expands. From our approach we also derive the temperature of the D0 branes
described by the matrix model, and show that they interpolate between a
radiation and a matter dominated era. |
