Adaptive Time Stepping for the Two-Time Integro-Differential Kadanoff-Baym Equations
Thomas Blommel, David J. Gardner, Carol S. Woodward +1
The non-equilibrium Green's function gives access to one-body observables for quantum systems. Of particular interest are quantities such as density, currents, and absorption spect…

Performance of wave function and Green's functions based methods for non equilibrium many-body dynamics
Cian C. Reeves, Gaurav Harsha, Avijit Shee +5
Theoretical descriptions of non equilibrium dynamics of quantum many-body systems essentially employ either (i) explicit treatments, relying on truncation of the expansion of the m…
