Out-of-time-ordered correlators for turbulent fields: a quantum-classical correspondence
Motoki Nakata
An extended formulation of out-of-time-ordered correlators (OTOCs), which quantify noncommutative operator growth and information scrambling in quantum many-body systems, is develo…

von Neumann entropy of phase space structures in gyrokinetic plasma turbulence
Go Yatomi, Motoki Nakata
We introduce a data-driven diagnostic that combines the singular value decomposition (SVD) with an information-theoretic entropy to quantify the phase-space complexity of perturbed…
