    Crystallization, Fermionization, and Cavity-Induced Phase Transitions of Bose-Einstein Condensates

    Bose-Einstein condensates (BECs) are one of the cornerstones in the exploration of the quantum many-body physics of interacting indistinguishable particles. Here, we study them using the MultiConfigurational T...

    Sorting Fermionization from Crystallization in Many-Boson Wavefunctions

    Fermionization is what happens to the state of strongly interacting repulsive bosons interacting with contact interactions in one spatial dimension. Crystallization is what happens for sufficiently strongly in...

    Exploring Many-Body Physics with Bose-Einstein Condensates

    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 i...

    Resonances and Dynamical Fragmentation in a Stirred Bose–Einstein Condensate

    Superfluids are distinguished from ordinary fluids by the quantized manner in which the rotation is manifested in them. Precisely, quantized vortices are known to appear in the bulk of a superfluid subject to ...

    Vortex Reconnections in Anisotropic Trapped Three-Dimensional Bose–Einstein Condensates

    Quantum vortex reconnections can be considered as a fundamental unit of interaction in complex turbulent quantum gases. Understanding the dynamics of single vortex reconnections as elementary events is an esse...
