For the past few years, SFI Professor David Wolpert and physicist Artemy Kolchinsky, a former SFI postdoctoral fellow, have been collaborating to better understand the connection between thermodynamics and information processing in computation. Their latest exploration of the topic, published in Physical Review E, looks at applying these ideas to a wide range of classical and quantum areas, including quantum thermodynamics.
In a study published in the Proceedings of the National Academy of Sciences, SFI External Professor Amy Bogaard and colleagues document the distribution of valuable artifacts across Southeast Asian gravesites over an era that spans from the Neolithic Period to the Agricultural Revolution.
In a new paper published in Physical Review X, SFI physicists David Wolpert and Artemy Kolchinsky explore more realistic bounds on entropy production by considering how constraints affect Landauer’s limit. Their approach to understanding how much work can be extracted from a physical system could lead to a better understanding of the thermodynamic efficiency of various real-world systems, ranging from biomolecular machines to recently-developed “information engines” that use information as fuel.
A new study by Santa Fe Institute researchers examines how scale affects factors like tuition, research production, and teaching salaries in different categories of colleges and universities. The research, published in PLOS ONE, is the first to systematically look at interconnected scaling effects in U.S. higher education.
Networks are a powerful model for describing connected systems in biological, physical, social, and other environments. As useful as they are, though, conventional networks are static and are limited to describing links between pairs of objects. In a paper published in Communications Physics, SFI Schmidt Science Fellow Yuanzhao Zhang and collaborators describe a new framework for simplifying the analysis of synchronization patterns in a wide variety of systems that include hypergraphs, temporal networks, and multilayer networks.
Is merit necessarily achieved, or does social status influence whether a person succeeds or is trapped in a system? Former SFI postdocs Eleanor Power and Marion Dumas, together with their colleague Jessica Barker, explore these questions in a new paper published in Philosophical Transactions of the Royal Society B.
In July, a virtual SFI. workshop began to investigate new ways of understanding how the brain computes using newly developed ideas in thermodynamics and information theory.
In February. of 2020, a small SFI working group convened to find the third signature of nonextensive statistical mechanics, namely the distribution of energies. They have published their results in a recent paper in the journal Nonlinear Dynamics.
Mathematicians call him an ecologist, ecologists call him a mathematician. SFI External Professor André de Roos is comfortable in interdisciplinary research settings, from Santa Fe to Sweden, where he is currently visiting Umea University's Integrated Science Lab on an H.M. King Carl XVI Gustaf Professorship in Environmental Science.
“In the still of the Tennessee night, my colleagues and I are watching thousands of dim little orbs of light, moving peacefully in the forest around us. We try to guess where the next flash will appear, but the movements seem erratic, even ephemeral,” writes SFI External Professor Orit Peleg in an op-ed about her research on firefly synchrony for Aeon.
In a new perspective piece for Nature, SFI External Professor Tina Eliassi-Rad and her co-authors ask how social scientists can investigate algorithmically infused societies, which may require very different methodologies than social sciences have traditionally deployed.
A new study presents a tool to assess research performance more fairly than the pervasive H-index score, which is commonly used to make hiring decisions in academia.
Much of modern sleep research has focused on the hormones, cells, and enzymes that regulate how we sleep, and what goes wrong when we can't sleep. But “all of this leaves unanswered the more fundamental question of why we need to sleep in the first place. What, in fact, is sleep’s function?” ask SFI's Van Savage and Geoffrey West in an essay for Aeon magazine.
Archaeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there’s never been a statistical fix that works — until now.
A team of researchers associated with the Evolution of Human Languages program is using a novel technique to comb through the data and to reconstruct major branches in the linguistic tree.
In a new opinion piece for Frontiers in Applied Mathematics and Statistics, SFI External Professor Jürgen Jost tours some of the major philosophical and scientific debates around consciousness, including whether a human or animal brain automatically becomes conscious when it crosses a certain threshold of complexity.
From small committees to national elections, group decision-making can be complicated — and it may not always settle on the best choice. A new mathematical framework shows that’s partly because some members of the group do research on their own, and others take their cues from the people around them.
On average, people in larger cities are better off economically. But a new study published in the Royal Society Interface builds on previous research that says, that’s not necessarily true for the individual city-dweller. It turns out, bigger cities also produce more income inequality.
What if life evolved not just once, but multiple times independently?
In a new paper, published in the Journal of Molecular Evolution, Santa Fe Institute researchers Chris Kempes and David Krakauer argue that in order to recognize life’s full range of forms, we must develop a new theoretical frame.
