Abstract

Bose-Einstein condensates (BECs) offer a fruitful, often uncharted ground for exploring physics of many-particle systems. In the present year of the MCTDHB project at the HLRS, we maintained and extended our investigations of BECs and interacting bosonic systems using the MultiConfigurational Time-Dependent Hartree for Bosons (MCTDHB) method and running the MCTDHB and MCTDH-X software packages on the Cray XC40 system Hazel Hen. The results we disseminate within this report comprise: (i) Entropies and correlations of ultracold bosons in a lattice; (ii) Crystallization of bosons with dipole-dipole interactions and its detection in single-shot images; (iii) Management of correlations in ultracold gases; (iv) Pulverizing a BEC; (v) Dynamical pulsation of ultracold droplet crystals by laser light; (vi) Two-component bosons interacting with photons in a cavity; (vii) Quantum dynamics of a bosonic Josephson junction and the impact of the range of the interaction; (viii) Trapped bosons in the infinite-particle limit and their exact many-body wavefunction and properties; (ix) Angular-momentum conservation in a BEC and Gross-Pitaevskii versus many-body dynamics; (x) Variance of an anisotropic BEC; and (xi) excitation spectrum of a weakly-interacting rotating BEC showing enhanced many-body effects. These are all basic and appealing, sometimes unexpected many-body results put forward with the generous allocation of computer time by the HLRS to the MCTDHB project. Finally, expected future developments and research tasks are prescribed, too.
