abstract = {Obtaining dynamics of an interacting quantum many-body system connected to multiple baths initially at
different, finite, temperatures and chemical potentials is a challenging problem. This is due to a combination
of the prevalence of strong correlations in the system, the infinite nature of the baths and the long time to reach
steady state. In this paper, we develop a general formalism that allows access to the full non-Markovian dynamics
of such open quantum many-body systems up to the nonequilibrium steady state, provided its uniqueness.
Specifically, we show how finite-time evolution in the presence of finite-sized baths, whose opportune size
is determined by their original spectral density, can be recursively used to faithfully reconstruct the exact
dynamics without requiring any small parameter. Such a reconstruction is possible even in parameter regimes
which would otherwise be inaccessible by current state-of-the-art techniques. We specifically demonstrate this
by obtaining the full numerically exact non-Markovian dynamics of interacting fermionic chains in two terminal
setups with finite temperature and voltage biases, a problem which previously remained outstanding despite its
relevance in a wide range of contexts, for example, quantum heat engines and refrigerators.},
