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…

Convergence study of multi-field singular value decomposition for turbulence fields
Go Yatomi, Motoki Nakata
Convergence of a matrix decomposition technique, the multi-field singular value decomposition (MFSVD) which efficiently analyzes nonlinear correlations by simultaneously decomposin…

Quantum-inspired information entropy in multi-field turbulence
Go Yatomi, Motoki Nakata
A novel information entropy of turbulence systems with multiple field quantities is formulated. Inspired by quantum mechanics, the von Neumann entropy (vNE) and the entanglement en…
