Geometrical interpretation of Hall conductivity in metals
Osamu Narikiyo
The weak-field Hall conductivity in metals is interpreted in terms of the curvature of the Fermi surface in the main part. In the appendix the orbital magnetic-susceptibility and t…
Fermi-Surface Curvature and Hall Conductivity in Metals
Osamu Narikiyo
The Tsuji formula which relates the Fermi-surface curvature and the weak-field Hall conductivity in metals is discussed in Haldane's framework.
Spectral function method for Hall conductivity of incoherent metals
Osamu Narikiyo
Using a model spectral function of the electron the Hall conductivity in the normal metallic state of the Pr_{2-x}Ce_xCuO_4 (PCCO) superconductor is calculated neglecting the curre…
Entropic Approach to Error-Disturbance Tradeoff in Quantum Measurements
Daigo Watanabe, Osamu Narikiyo
We discuss the relation between entropic uncertainty relations by Buscemi et al. and by Barchielli et al.
Ward identities for charge and heat currents of particle-particle and particle-hole pairs
Osamu Narikiyo
The Ward identities for the charge and heat currents are derived for particle-particle and particle-hole pairs. They are the exact constraints on the current-vertex functions impos…
Early Evolution of Bird-Type Language without Grammar: Duplication and Mutation
Miki Fukunoue, Osamu Narikiyo
Using a series of computer simulations we have demonstrated a scenario of the early evolution of the bird-type primitive language. We do not assume wise agents who can use a gramma…
