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…
Quantum fluctuations approach to the nonequilibrium approximation
Erik Schroedter, Jan-Philip Joost, Michael Bonitz
The quantum dynamics of fermionic or bosonic many-body systems following external excitation can be successfully studied using two-time nonequilibrium Green's functions (NEGF) or s…
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…
