Research Impact

1. AIP has found it newsworthy to accord our newly published article "Thermodynamic susceptibility as a measure of cooperative behavior in social dilemmas" in Chaos with a press release. The press release is interestingly titled "Betrayal or cooperation? Analytical investigation of behavior drivers" and comes with the following tag line- Using game magnetization and susceptibility in an analytic investigation of cooperation with infinite numbers of people. It has been picked up by some of the most prominent science news portals, like EurekAlert https://www.eurekalert.org/pub_releases/2020-09/aiop-boc090320.php
   also by PHYS.ORG https://phys.org/news/2020-09-betrayal-cooperation-analytical-behavior-drivers.html

   and ScienceDaily https://www.sciencedaily.com/releases/2020/09/200908113235.htm

2. Our new publication in "Chaos" has been accorded the honor of a featured article. It looks at the problem of cooperative behavior with a new tool, thermodynamic susceptibility. While magnetization, the net difference in the fraction of cooperators and defectors is an extremely good macroscopic measure of cooperative behavior, susceptibility is a more sensitive probe for microscopic behavior, e.g., observing small changes in a population adopting a certain strategy. 

3. Our paper "The emergence of cooperation in the thermodynamic limit" has been published as a Letter to the Editor in Chaos, Solitons & Fractals.
