Physicists who do research on complex systems

Click For Summary

Discussion Overview

The discussion revolves around the classification of physicists researching complex systems and nonlinear dynamics, specifically whether they belong to the condensed matter physics community or represent a distinct field within physics. The scope includes theoretical perspectives and the academic categorization of researchers in this area.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest examining the departments, courses, and journals associated with researchers like Mark Newman, Jim Crutchfield, Doyne Farmer, and David Wolpert to determine their classification.
  • It is noted that some researchers in complex systems publish in journals such as Physical Review E and Journal of Complex Networks, which may indicate their alignment with specific fields.
  • One participant proposes consulting experienced condensed matter physicists who are familiar with the literature and events to gain insight into the classification of these researchers.
  • Historical figures in nonlinear dynamics, such as Feigenbaum, Lorenz, and Takens, are mentioned as having been classified as separate from condensed matter physics during their time, suggesting a historical precedent for such distinctions.
  • Stephen Strogatz and his collaborators are characterized as applied mathematicians, indicating that nonlinear dynamics and complexity may also be viewed through the lens of applied mathematics rather than strictly physics.

Areas of Agreement / Disagreement

Participants express differing views on whether researchers in complex systems should be classified within the condensed matter physics community or as part of a separate field. The discussion remains unresolved, with multiple perspectives presented.

Contextual Notes

Participants highlight the importance of academic affiliations and publication venues in determining the classification of researchers, but there is no consensus on the implications of these factors.

Hi everyone. I have followed with interest in the work of physicists who have conducted research in the area of complex systems and nonlinear dynamics. For example, consider researchers such as Mark Newman from the University of Michigan, Jim Crutchfield of USC, or Doyne Farmer and David Wolpert of the Santa Fe Institute.

Would you consider these people to be part of the condensed matter physics theory community of researchers (given their common background in statistical physics)? Or is it best to think of these researchers as a separate, entirely distinct of physics?

The best way to answer this is to see:
- what departments they are in at their universities or companies or
- what courses they teach or
- what journals they typically submit to.

In the case of some of the physicists that I'm aware of who do research on complex systems, they have submitted their publications to journals such as Physical Review E (covering statistical nonlinear, biological and soft matter physics), Journal of Complex Networks (which, as the title suggests, is a journal that specializes in complex networks research).

This doesn't really answer my question about whether these researchers are part of the condensed matter physics community.
 
^ Try asking experienced condensed matter physicists; assuming they are familiar with the literature and go to CMP events, they should be able to answer you directly.

Some big "old" names in nonlinear dynamics (NLD) and complexity are Feigenbaum, Lorenz and Takens. They all were instrumental in the early 'nonlinear revolution' and obviously pioneers of the field, but while they were working back then they would most definitely all be classified as completely separate scientists working in completely separate fields.

Stephen Strogatz, of the masterful NLD textbook, and many of his students and collaborators, including Watts and Barabasi, would probably be classified as applied mathematicians; incidentally, nonlinear dynamics, chaos and complexity are also best classified as applied mathematics.
