Practical unitary simulator for non-Markovian complex processes

FC Binder, J Thompson, M Gu - Physical review letters, 2018 - APS
Stochastic processes are as ubiquitous throughout the quantitative sciences as they are
notorious for being difficult to simulate and predict. In this Letter, we propose a unitary …

Multivariate dependence beyond Shannon information

RG James, JP Crutchfield - Entropy, 2017 - mdpi.com
Accurately determining dependency structure is critical to understanding a complex system's
organization. We recently showed that the transfer entropy fails in a key aspect of this …

The origins of computational mechanics: A brief intellectual history and several clarifications

JP Crutchfield - arXiv preprint arXiv:1710.06832, 2017 - arxiv.org
The principle goal of computational mechanics is to define pattern and structure so that the
organization of complex systems can be detected and quantified. Computational mechanics …

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 …

G Minati, E Pessa, G Minati, E Pessa - 2018 - Springer
This chapter is dedicated to explore among different post-GOFS systemic properties of
different nature like ones considered above and based on the concepts of quasi already …

Order and information in the patterns of spinning magnetic micro-disks at the air-water interface

W Wang, G Gardi, P Malgaretti, V Kishore, L Koens… - Science …, 2022 - science.org
The application of the Shannon entropy to study the relationship between information and
structures has yielded insights into molecular and material systems. However, the difficulty in …

Structure and randomness of continuous-time, discrete-event processes

SE Marzen, JP Crutchfield - Journal of Statistical Physics, 2017 - Springer
Loosely speaking, the Shannon entropy rate is used to gauge a stochastic process' intrinsic
randomness; the statistical complexity gives the cost of predicting the process. We calculate …

[HTML][HTML] Influence of modelling disorder on Hirshfeld atom refinement results of an organo-gold (I) compound
