1204.6435 (Jose L. F. Barbon et al.)

Fast Scramblers, Horizons and Expander Graphs    [PDF]

Jose L. F. Barbon, Javier M. Magan
We propose that local quantum systems defined on expander graphs provide a simple microscopic model for thermalization on quantum horizons. Such systems are automatically fast scramblers and are motivated from the membrane paradigm by a conformal transformation to the so-called optical metric.
