This provides a general data-driven approach for studying the internal physical behavior of metallic (but also other types of) systems just by building on the abstract concepts of fluctuations & spatiotemporal fluctuations' correlations. 🀯🀩

Our analyses demonstrate, in a completely unsupervised & abstract way, how metal lattices transition from the elastic to the plastic phase when new local defects/fluctuations cannot avoid emerging as correlated in space & simultaneous in time, leading to the early emergence of dislocations! πŸ€“

In non-cooperative systems, all entities populating them suffer comparably from external perturbations.
In cooperative systems (with internal "interactions-avidity"), the stronger units survive at the expense of the weaker ones!🀯

Glad to see a section on our 2017 work www.nature.com/articles/s41... explaining via models/simulations how the dynamics of supramolecular polymers is controlled by defects, later observed by experiments @fluorenzo.bsky.social in 2024 (pubs.acs.org/doi/10.1021/...)!

#LEAP analyses are agnostic & require just that a trajectory of the building blocks constituting the complex dynamical system is available.
Particularly useful to explore complex dynamical systems whose physics is unknown a priori, as well as to revisit wel-known phenomena under a new perspective.🀯

#LEAP analyses allow to:
1) Detect relevant fluctuations from noise in trajectories
2) Classify fluctuations in types based on their physics
3) Identifying correlations in space & time between fluctuations
4) Unveil local & collective events, their correlations, causal relationships, etc.

with this approach the choice of the best cutoff distance or of the time intervals between the studied frames stop being parameters to be tuned in the analysis, but steps out as automatically encoded into the data: these are those allowing to maximise information extraction from the data itself!πŸš€πŸ”₯
