Some Exact Properties of the Nonequilibrium Response Function for Transient Photoabsorption
The physical interpretation of time-resolved photoabsorption experiments is not as straightforward as for the more conventional photoabsorption experiments conducted on equilibrium systems. In fact,Expand

Charge dynamics in molecular junctions: Nonequilibrium Green's function approach made fast
Real-time Green's function simulations of molecular junctions (open quantum systems) are typically performed by solving the Kadanoff-Baym equations (KBE). The KBE, however, impose a seriousExpand

Time-dependent Landauer-Buttiker formula: application to transient dynamics in graphene nanoribbons
In this work we develop a time-dependent extension of the Landauer-Buttiker approach to study transient dynamics in time-dependent quantum transport through molecular junctions. A key fea- ture ofExpand

The Dissection Algorithm for the Second‐Born Self‐Energy
We describe an algorithm to efficiently compute the second-Born self-energy of many-body perurbation theory. The core idea consists in dissecting the set of all four-index Coulomb integrals intoExpand

Critical currents in graphene Josephson junctions
We study the superconducting correlations induced in graphene when it is placed between two superconductors, focusing in particular on the supercurrents supported by the 2D system. For this purposeExpand

First-principles approach to excitons in time-resolved and angle-resolved photoemission spectra
In this work we put forward a first-principles approach and propose an accurate diagrammatic approximation to calculate the time-resolved (TR) and angle-resolved photoemission spectrum of systemsExpand

Time-dependent quantum transport with superconducting leads: A discrete-basis Kohn-Sham formulation and propagation scheme
In this work we put forward an exact one-particle framework to study nanoscale Josephson junctions out of equilibrium and propose a propagation scheme to calculate the time-dependent current inExpand

First-principles nonequilibrium Green's-function approach to transient photoabsorption: Application to atoms
We put forward a first-principle nonequilibrium Green’s-function (NEGF) approach to calculate the transient photoabsorption spectrum of optically thin systems. The method can deal with pump fields ofExpand

Suppression of electron?electron repulsion and superconductivity in ultra-small carbon nanotubes
Recently, ultra-small diameter single wall nanotubes with diameter of ~0.4 nm have been produced and many unusual properties were observed, such as superconductivity, leading to a transitionExpand

CHEERS: a tool for correlated hole-electron evolution from real-time simulations.
We put forward a practical nonequilibrium Green's function (NEGF) scheme to perform real-time evolutions of many-body interacting systems driven out of equilibrium by external fields. CHEERS is aExpand
