Comparison of the Kubo formula, the microscopic response method, and the Greenwood formula.
For a mechanical perturbation, the microscopic response method is equivalent to and more convenient to use than the Kubo formula. When the gradient of the carrier density is small, the current density reduces to that used by Greenwood.
متن کاملKubo-Greenwood electrical conductivity formulation and implementation for projector augmented wave datasets
As the foundation for a new computational implementation, we survey the calculation of the complex electrical conductivity tensor based on the KuboGreenwood (KG) formalism (J. Phys. Soc. Jpn. 12, 570 (1957); Proc. Phys. Soc. 71, 585 (1958)), with emphasis on derivations and technical aspects pertinent to use of projector augmented wave datasets with plane wave basis sets (Phys. Rev. B 50, 17953...
متن کاملExact time-averaged thermal conductance for small systems: comparison between direct calculation and Green-Kubo formalism.
In this paper, we study exactly the thermal conductance for a low dimensional system represented by two coupled massive Brownian particles, both directly and via a Green-Kubo expression. Both approaches give exactly the same result. We also obtain exactly the steady-state probability distribution for that system by means of time averaging.
متن کاملStochastic rotation dynamics. I. Formalism, Galilean invariance, and Green-Kubo relations.
A detailed analytical and numerical analysis of a recently introduced stochastic model for fluid dynamics with continuous velocities and efficient multi-particle collisions is presented. It is shown how full Galilean invariance can be achieved for arbitrary Mach numbers and how other low temperature anomalies can be removed. The relaxation towards thermal equilibrium is investigated numerically...
متن کاملProperties of Localization Using Distance-Differences
We study several basic properties related to the task of localizing a source using distance-difference measurements to it. These properties enable minimalistic realizations of localization systems. We establish conditions for the unique identification of a source in Euclidean plane, and derive minimum number of sensors needed for unique source identification within the Euclidean plane and a pol...
