Database of Unstable Periodic Orbits (UPOs) up to Period-20 for a Bistable Energy Harvester

This repository contains a deep topological dataset of Unstable Periodic Orbits (UPOs) extracted from a chaotic bistable energy harvesting system. The database includes 1,106,388 UPOs up to topological length $n=20$. This dataset is designed to facilitate research in Periodic Orbit Theory, Cycle Expansion, chaotic dynamics, and topological data analysis. It provides the discrete spatial coordinates and stability multipliers necessary to reconstruct the dynamical zeta function and evaluate ergodic averages.
