Phase space gradient of dissipated work and information: A role of relative Fisher information
Takuya Yamano
We show that an information theoretic distance measured by the relative Fisher information between canonical equilibrium phase densities corresponding to forward and backward proce…
de Bruijn-type identity for systems with flux
Takuya Yamano
We show that an information-theoretic relation called the de Bruijn-type identity can be reformulated in a physical context with probability currents. The time derivatives of relat…
Fluctuation of gauge field for general nonlinear Fokker-Planck equation and covariant version of Fisher information matrix
Takuya Yamano
We clarify a strong link between general nonlinear Fokker-Planck equations with gauge fields associated with nonequilibrium dynamics and the Fisher information of the system. The n…
Bounds for Fisher information and its production under flow
Takuya Yamano
We prove that two well-known measures of information are interrelated in interesting and useful ways when applied to nonequilibrium circumstances. A nontrivial form of the lower bo…
A generalization of the Kullback-Leibler divergence and its properties
Takuya Yamano
A generalized Kullback-Leibler relative entropy is introduced starting with the symmetric Jackson derivative of the generalized overlap between two probability distributions. The g…
Double Power Law Decay of the Persistence in Financial Markets
S. Jain, T. Yamano
The persistence phenomenon is studied in the Japanese financial market by using a novel mapping of the time evolution of the values of shares quoted on the Nikkei Index onto Ising…
