Correlation effects in bistability at the nanoscale: steady state and beyond
E. Khosravi, A. -M. Uimonen, A. Stan +4
The possibility of finding multistability in the density and current of an interacting nanoscale junction coupled to semi-infinite leads is studied at various levels of approximati…
Comparative study of many-body perturbation theory and time-dependent density functional theory in the out-of-equilibrium Anderson model
A. -M. Uimonen, E. Khosravi, A. Stan +4
We study time-dependent electron transport through an Anderson model. The electronic interactions on the impurity site are included via the self-energy approximations at Hartree-Fo…
Phononic Self energy effects and superconductivity in CaC
A. Sanna, S. Pittalis, J. K. Dewhurst +5
We study the graphite intercalated compound CaC by means of Eliashberg theory, focusing on the anisotropy properties. An analysis of the electron-phonon coupling is performed,…
Bootstrap approximation for the exchange-correlation kernel of time-dependent density functional theory
S. Sharma, J. K. Dewhurst, A. Sanna +1
A new parameter-free approximation for the exchange-correlation kernel of time-dependent density functional theory is proposed. This kernel is expressed as an algorith…
Electronic structure via potential functional approximations
Attila Cangi, Donghyung Lee, Peter Elliott +2
The universal functional of Hohenberg-Kohn is given as a coupling-constant integral over the density as a functional of the potential. Conditions are derived under which potential-…
