Here, Zanin and Olivares review the permutation patterns-based metrics used to distinguish chaos from stochasticity in discrete time series. They analyse their performance and computational cost, and compare their applicability to real-world time series.

Topological materials are extensively studied in condensed matter physics and several have been studied to the point where it is now time to ask if these unique materials have a role to play in next generation technologies. The author reviews the current status of well-characterized topological materials such as Bi₂Se₃ for electronic device applications, focusing on selected technological aspects and their promise for engineering applications.
