Hessian-based Lagrangian closure theory for passive scalar turbulence
Taketo Ariki, Kyo Yoshida
Self-consistent closure theory for passive-scalar turbulence has been developed on the basis of the Hessian of the scalar field. As a primitive indicator of spatial structure of th…

Boltzmann entropy for quantum field systems
Kyo Yoshida
A way to construct Boltzmann entropy, i.e., the entropy as a function of a microscopic pure state, for quantum field systems is proposed. Operators that shift the field in wavevect…
