Improved master equation approach to quantum transport: from Born to self-consistent Born approximation.
Beyond the second-order Born approximation, we propose an improved master equation approach to quantum transport under self-consistent Born approximation. The basic idea is to replace the free Green's function in the tunneling self-energy diagram by an effective reduced propagator under the Born approximation. This simple modification has remarkable consequences. It not only recovers the exact ...
متن کاملSelf-consistent model of fermions
Abstract: A composite model of fermions based on three-flavoured preons is presented. It is shown that the opposite character of interactions between preons leads to formation of complex structures reproducing three generations of quarks and leptons with all their quantum numbers and masses. The model is self-consistent (it doesn’t use input parameters). Nevertheless, the masses of the generate...
متن کاملExploring the limits of the self consistent Born approximation for inelastic electronic transport
The non equilibrium Green function formalism is today the standard computational method for describing elastic transport in molecular devices. This can be extended to include inelastic scattering by the so called self-consistent Born approximation (SCBA), where the interaction of the electrons with the vibrations of the molecule is assumed to be weak and it is treated perturbatively. The validi...
متن کاملDegenerate perturbation theory corrections for the vibrational self-consistent field approximation: Method and applications
A new algorithm for computing anharmonic vibrational states for polyatomic molecules is proposed. The algorithm starts with the vibrational self-consistent field ~VSCF! method and uses degenerate perturbation theory to correct for effects of correlation between different vibrational modes. The algorithm is developed in a version that computes the anharmonic vibrational spectroscopy directly fro...
متن کاملOverlap for Majorana–weyl Fermions
The power of the overlap formalism is illustrated by regularizing theories based on Majorana-Weyl fermions. The results reported in this contribution were obtained in collaboration with Patrick Huet [1]. More than half of the talk will be independent of the overlap formalism. To present our ideas in the simplest context possible we start directly from an example. Consider a U (1) chiral model, ...
