“Ergodicity of Complex Orbits in Julia Set Explains Tunneling Tails in Nonintegrable Systems”

https://pubmed.ncbi.nlm.nih.gov/38115491

This study reveals that the ergodicity of complex orbits in the Julia set enables connection between arbitrary regions in nonintegrable systems, providing an alternative to the instanton path and influencing the emergence of nontrivial tunneling tails with both imaginary and real action contributions.
