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…
A Diagrammer's Note on Superconducting Fluctuation Transport for Beginners: Supplement. Boltzmann Equation and Fermi-Liquid Theory
Osamu Narikiyo
The effect of the collision term of the Boltzmann equation is discussed for the diagonal conductivity in the absence of magnetic field and the off-diagonal conductivity within the…
A Diagrammer's Note on Superconducting Fluctuation Transport for Beginners: Supplement. Jonson-Mahan Transmutation
Osamu Narikiyo
The Ward identity for the heat current vertex is illustrated in terms of Feynman diagrams. The Jonson-Mahan transmutation, the way how the kinetic energy at the heat current vertex…
Ward identities for extended objects
Osamu Narikiyo
Ward identities for extended objects are discussed. In the limit of dc transport it is rigorously proved that charge-density and spin-density fluctuations do not couple to electrom…
A Diagrammer's Note on Superconducting Fluctuation Transport for Beginners: II. Hall and Nernst Effects with Perturbational Treatment of Magnetic Field
Osamu Narikiyo
A diagrammatic approach based on thermal Green function to superconducting fluctuation transport is reviewed focusing on Hall and Nernst effects. The treatment of weak magnetic fie…
A Diagrammer's Note on Superconducting Fluctuation Transport for Beginners: I. Conductivity and Thermopower
Osamu Narikiyo
A diagrammatic approach based on thermal Green function to superconducting fluctuation transport is reviewed keeping consistency with Ginzburg-Landau theory. The correct expression…
