Dipolar quantum droplets are exotic quantum objects that are self-bound due to the subtle balance of attraction, repulsion, and quantum correlations. Here we present a systematic study of the critical atom number of these self-bound droplets, compari

We study the repulsive Fermi polaron in a two-component, two-dimensional system of fermionic atoms inspired by the results of a recent experiment with 173Yb atoms [N. Darkwah Oppong et al., Phys. Rev. Lett. 122, 193604 (2019)]. We use the diffusion M

The study of changes in climate on the scale of the entire history of Earth requires absolute dating methods that cover the total time period. 230 Th and 234 U disequilibria, as well as 231 Pa and 235 U, have shown as good candidates to provide ages

We study the superfluid properties of a system of fully polarized dipolar bosons moving in the $XY$ plane. We focus on the general case where the polarization field forms an arbitrary angle $\ensuremath{\alpha}$ with respect to the $Z$ axis, while th
