Between order and chaos

JP Crutchfield - Nature Physics, 2012 - nature.com
What is a pattern? How do we come to recognize patterns never seen before? Quantifying
the notion of pattern and formalizing the process of pattern discovery go right to the heart of …

Chaotic crystallography: How the physics of information reveals structural order in materials

DP Varn, JP Crutchfield - Current Opinion in Chemical Engineering, 2015 - Elsevier
We review recent progress in applying information-theoretic and computation-theoretic
measures to describe material structure that transcends previous methods based on exact …

Bayesian structural inference for hidden processes

CC Strelioff, JP Crutchfield - Physical Review E, 2014 - APS
We introduce a Bayesian approach to discovering patterns in structurally complex
processes. The proposed method of Bayesian structural inference (BSI) relies on a set of …

What did Erwin mean? The physics of information from the materials genomics of aperiodic crystals and water to molecular information catalysts and life

DP Varn, JP Crutchfield - Philosophical Transactions of …, 2016 - royalsocietypublishing.org
Erwin Schrödinger famously and presciently ascribed the vehicle transmitting the hereditary
information underlying life to an 'aperiodic crystal'. We compare and contrast this, only later …

∊-Machine spectral reconstruction theory: a direct method for inferring planar disorder and structure from X-ray diffraction studies
