The nonequilibrium dynamics of strongly-correlated fermions in lattice systems have attracted considerable interest in the condensed matter and ultracold atomic-gas communities. While experiments have made remarkable progress in recent years, there remains a need for the further development of theoretical tools that can account for both the nonequilibrium conditions and strong correlations. For instance, time-dependent theoretical quantum approaches based on the density matrix renormalization… 
Ultrafast dynamics of strongly correlated fermions -- Nonequilibrium green functions and selfenergy approximations.
A selfcontained introduction to the theory of NEGF is presented and an overview on recent numerical applications to compute the ultrafast relaxation dynamics of correlated fermions is given.
Löwdin's symmetry dilemma within Green functions theory for the one‐dimensional Hubbard model
The energy gap of correlated Hubbard clusters is well studied for one‐dimensional systems using analytical methods and density‐matrix‐renormalization‐group (DMRG) simulations. Beyond 1D, however,
Achieving the Scaling Limit for Nonequilibrium Green Functions Simulations.
It is demonstrated that GKBA-NEGF simulations can be performed with order T^{1} scaling, both for SOA and GW selfenergies, and pointed out the remarkable capabilities of this approach.
Quantum Boltzmann equation for strongly correlated systems: Comparison to dynamical mean field theory
We investigate the potential of a quantum Boltzmann equation without momentum conservation for description of strongly correlated electron systems out of equilibrium. In a spirit similar to dynamical
Ion Impact Induced Ultrafast Electron Dynamics in Finite Graphene‐Type Hubbard Clusters
Strongly correlated systems of fermions have an interesting phase diagram arising from the Hubbard gap. Excitation across the gap leads to the formation of doubly occupied lattice sites (doublons)
Quantum dynamics of impenetrable SU(N) fermions in one-dimensional lattices
We study quantum quench dynamics in the Fermi-Hubbard model, and its SU($N$) generalizations, in one-dimensional lattices in the limit of infinite onsite repulsion between all flavors. We consider
Theoretical Developments for the Real-Time Description and Control of Nanoscale Systems
In this thesis we focus on improvements of the description of the electron-electron correlation effects in nonequilibrium nanosystems. We mainly focus on developments of two nonequilibrium methods,
Real-time evolution in the Hubbard model with infinite repulsion
We consider the real-time evolution of the Hubbard model in the limit of infinite coupling. In this limit the Hamiltonian of the system is mapped into a number-conserving quadratic form of spinless
Fast Green's Function Method for Ultrafast Electron-Boson Dynamics.
A real-time study of the phonon-driven relaxation dynamics in an optically excited narrow band-gap insulator, highlighting the nonthermal behavior of the voiceless degrees of freedom and paving the way to first-principles simulations of electron-boson systems with unprecedented long propagation times.
Ultrafast nonequilibrium evolution of excitonic modes in semiconductors
We study the time evolution of excitonic states after photo-excitation in the one-dimensional spinless extended Falikov-Kimball model. Several numerical methods are employed and benchmarked against

The preceding formulation of statistical mechanics is perhaps the simplest application of probability theory to the many-body problem. Although it is consistent with the principles of quantum
