Accelerating Nonequilibrium Green functions simulations with embedding selfenergies
Karsten Balzer, Niclas Schlünzen, Hannes Ohldag +2
Real-time nonequilibrium Green functions (NEGF) have been very successful to simulate the dynamics of correlated many-particle systems far from equilibrium. However, NEGF simulatio…
The dynamically screened ladder approximation: Simultaneous treatment of strong electronic correlations and dynamical screening out of equilibrium
Jan-Philip Joost, Niclas Schlünzen, Hannes Ohldag +3
Dynamical screening is a key property of charged many-particle systems. Its theoretical description is based on the approximation that is extensively applied for ground-state…
Doublon production in correlated materials by multiple ion impacts
Lotte Borkowski, Niclas Schlünzen, Jan Philip Joost +2
In a recent Letter [Balzer \textit{et al.}, Phys. Rev. Lett. \textbf{121}, 267602 (2018)] it was demonstrated that ions impacting a correlated graphene cluster can excite strongly…
Toward a Nonequilibrium Green functions approach to diffusion in strongly coupled finite quantum systems
M. Bonitz, N. Schluenzen, S. Hermanns
Transport properties of strongly correlated quantum systems are of central interest in condensed matter, ultracold atoms and in dense plasmas. There, the proper treatment of strong…
