Electronic Density Response of Warm Dense Matter
Tobias Dornheim, Zhandos A. Moldabekov, Kushal Ramakrishna +11
Matter at extreme temperatures and pressures -- commonly known as warm dense matter (WDM) in the literature -- is ubiquitous throughout our Universe and occurs in a number of astro…
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…
Electronic pair alignment and roton feature in the warm dense electron gas
Tobias Dornheim, Zhandos Moldabekov, Jan Vorberger +2
The study of matter under extreme densities and temperatures as they occur e.g. in astrophysical objects and nuclear fusion applications has emerged as one of the most active front…
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…
