Nonequilibrium electron-phonon dynamics with high momentum resolution: Thermalization bottlenecks and the effects of phonon dispersion

Maksymilian Środa, Maksymilian Środa, Philipp Werner

The nonequilibrium interplay of electrons and phonons plays an important role in the thermalization of solids, yet the microscopic picture of transient states and relaxation pathwa…

A causality-based divide-and-conquer algorithm for nonequilibrium Green's function calculations with quantics tensor trains

Ken Inayoshi, Maksymilian Środa, Anna Kauch +2

We propose a causality-based divide-and-conquer algorithm for nonequilibrium Green's function calculations with quantics tensor trains. This algorithm enables stable and efficient…

Memory-Efficient Nonequilibrium Green's Function Framework Built On Quantics Tensor Trains

Maksymilian Środa, Ken Inayoshi, Hiroshi Shinaoka +1

One of the challenges in diagrammatic simulations of nonequilibrium phenomena in lattice models is the large memory demand for storing momentum-dependent two-time correlation funct…

Predictor-corrector method based on dynamic mode decomposition for tensor-train nonequilibrium Green's function calculations

Maksymilian Środa, Ken Inayoshi, Michael Schüler +2

The nonequilibrium Green's function (NEGF) formalism is a powerful tool to study the nonequilibrium dynamics of correlated lattice systems, but its applicability to realistic syste…
