Mesoscopic thermal transport through a weak link
We consider mesoscopic thermal transport between two bulk dielectrics joined by a narrow wire or weak mechanical link. In the ‘‘tunneling’’ regime where the phonon transmission probability through the link is small and the thermal conductance is much less than pk BT=6_; the thermal current is determined by a product of the local vibrational spectral densities of the two bodies. We derive an exp...
متن کاملQuantum Transport with Spin Dephasing: A Nonequilibrium Green's Function Approach
A quantum transport model incorporating spin scattering processes is presented using the non-equilibrium Green's function (NEGF) formalism within the self-consistent Born approximation. This model offers a unified approach by capturing the spin-flip scattering and the quantum effects simultaneously. A numerical implementation of the model is illustrated for magnetic tunnel junction devices with...

متن کاملTime-dependent transport through single molecules: nonequilibrium Greens functions and TDDFT
The nomenclature quantum transport has been coined for the phenomenon of electron motion through constrictions of transverse dimensions smaller than the electron wavelength, e.g., quantum-point contacts, quantum wires, molecules, etc. To describe transport properties on such a small scale, a quantum theory of transport is required. In this section we focus on quantum transport problems whose ex...
متن کاملQuantum master-equation approach to quantum transport through mesoscopic systems
For quantum transport through mesoscopic systems, a quantum master-equation approach is developed in terms of compact expressions for the transport current and the reduced density matrix of the system. The present work is an extension of Gurvitz’s approach for quantum transport and quantum measurement, namely, to finite temperature and arbitrary bias voltage. Our derivation starts from a second...
