Two-Time Quantum Fluctuations Approach and its Relation to the Bethe--Salpeter Equation
Erik Schroedter, Michael Bonitz
Correlated quantum many-particle systems out of equilibrium are of high interest in many fields, including correlated solids, ultracold atoms or dense plasmas. Accurate theoretical…
Accelerating Nonequilibrium Green functions simulations: the G1-G2 scheme and beyond
Michael Bonitz, Jan-Philip Joost, Christopher Makait +3
The theory of Nonequilibrium Green functions (NEGF) has seen a rapid development over the recent three decades. Applications include diverse correlated many-body systems in and out…
Quantum Fluctuations Approach to the Nonequilibrium -Approximation II: Density Correlations and Dynamic Structure Factor
Erik Schroedter, Björn Jakob Wurst, Jan-Philip Joost +1
The quantum dynamics of correlated fermionic or bosonic many-body systems following external excitation can be successfully studied using nonequilibrium Green functions (NEGF) or r…
