Luminous matter may arise from a turbulent plasma state of the early universe
Per Bak, Maya Paczuski
The almost perfect uniformity of the cosmic microwave background (CMB) radiation, discovered by Penzias and Wilson in 1965 appears to present clearcut evidence that the universe wa…
Unified Scaling Law for Earthquakes
Per Bak, Kim Christensen, Leon Danon +1
We show that the distribution of waiting times between earthquakes occurring in California obeys a simple unified scaling law valid from tens of seconds to tens of years, see Eq. (…
Spatial competition and price formation
Kai Nagel, Martin Shubik, Maya Paczuski +1
We look at price formation in a retail setting, that is, companies set prices, and consumers either accept prices or go someplace else. In contrast to most other models in this con…
Self-Organized Criticality in a Transient System
Simon F. Norrelykke, Per Bak
A simple model economy with locally interacting producers and consumers is introduced. When driven by extremal dynamics, the model self-organizes {\em not} to an attractor state, b…
Scale Dependent Dimension of Luminous Matter in the Universe
Per Bak, Kan Chen
We present a geometrical model of the distribution of luminous matter in the universe, derived from a very simple reaction-diffusion model of turbulent phenomena. The apparent dime…
