Abstract: 
This 2021 report summarizes our activities at the HLRS facilities Hawk and Hazel Hen in the framework of the multiconfigurational time-dependent Hartree for indistinguishable particles (MCTDH-X) high-performance computation project. Our results are a bottom-up investigation into exciting and intriguing many-body physics and phase diagrams obtained via the direct solution of the Schrödinger equation and its comparison to experiments, and via machine learning approaches.We investigated ultracold-boson quantum simulators for crystallization and superconductors in a magnetic field, the phase transitions of ultracold bosons interacting with a cavity and of charged fermions in lattices described by the Falicov-Kimball model. Moreover, we report exciting findings on the many-body dynamics of tunneling and variances, in two and three-dimensional ultracold-boson systems, respectively.
