Hall Coefficient of Equilibrium Supercurrents Flowing inside Superconductors
Takafumi Kita
We study augmented quasiclassical equations of superconductivity with the Lorentz force, which is missing from the standard Ginzburg-Landau and Eilenberger equations. It is shown t…
Entropy Change through Rayleigh-Bénard Convective Transition with Rigid Boundaries
Takafumi Kita
The previous investigation on Rayleigh-Bénard convection of a dilute classical gas [T. Kita: J. Phys. Soc. Jpn. {\bf 75} (2006) 124005] is extended to calculate entropy change of t…
Principle of Maximum Entropy Applied to Rayleigh-Bénard Convection
Takafumi Kita
A statistical-mechanical investigation is performed on Rayleigh-Bénard convection of a dilute classical gas starting from the Boltzmann equation. We first present a microscopic der…
Entropy in Nonequilibrium Statistical Mechanics
Takafumi Kita
Entropy in nonequilibrium statistical mechanics is investigated theoretically so as to extend the well-established equilibrium framework to open nonequilibrium systems. We first de…
Conserving Gapless Mean-Field Theory of a Multi-Component Bose-Einstein Condensate
Yoshiyuki Kondo, Takafumi Kita
We develop a mean-field theory for Bose-Einstein condensation of spin-1 atoms with internal degrees of freedom. It is applicable to nonuniform systems at finite temperatures with a…
Conserving Gapless Mean-Field Theory for Weakly Interacting Bose Gases
Takafumi Kita
This paper presents a conserving gapless mean-field theory for weakly interacting Bose gases. We first construct a mean-field Luttinger-Ward thermodynamic functional in terms of th…
