Dynamical equations for time-ordered Green's functions: from the Keldysh time-loop contour to equilibrium at finite and zero temperature
H. Ness, L. K. Dash
We study the dynamical equation of the time-ordered Green's function at finite temperature. We show that the time-ordered Green's function obeys a conventional Dyson equation only…
Non-equilibrium renormalised contacts for transport in nanodevices with interaction: a quasi-particle approach
H. Ness, L. K. Dash
We present an application of a new formalism to treat the quantum transport properties of fully interacting nanoscale junctions. We consider a model single-molecule nanojunction in…
Non-equilibrium transport with self-consistent renormalised contacts for a single-molecule nanodevice with electron-vibron interaction
H. Ness, L. K. Dash
We present an application of a new formalism to treat the quantum transport properties of fully interacting nanoscale junctions [Phys. Rev. B {\bf 84}, 235428 (2011)]. We consider…
Many-body current formula and current conservation for non-equilibrium fully interacting nanojunctions
H. Ness, L. K. Dash
We consider the electron transport properties through fully interacting nanoscale junctions beyond the linear-response regime. We calculate the current flowing through an interacti…
Non-equilibrium charge susceptibility and dynamical conductance: Identification of scattering processes in quantum transport
H. Ness, L. K. Dash
We calculate the non-equilibrium charge transport properties of nanoscale junctions in the steady state and extend the concept of charge susceptibility to the non-equilibrium condi…
Functionality in single-molecule devices: Model calculations and applications of the inelastic electron tunneling signal in molecular junctions
L. K. Dash, H. Ness, M. J. Verstraete +1
We analyze how functionality could be obtained within single-molecule devices by using a combination of non-equilibrium Green's functions and ab-initio calculations to study the in…
