Signatures of the BCS-BEC crossover in the yrast spectra of Fermi quantum rings
Ulrich Ebling, Ali Alavi, Joachim Brand
We study properties of the lowest energy states at non-zero total momentum (yrast states) of the Hubbard model for spin-1/2 fermions in the quantum ring configuration with attracti…

Eliminating the wave function singularity for ultracold atoms by similarity transformation
Péter Jeszenszki, Ulrich Ebling, Hongjun Luo +2
A hyperbolic singularity in the wave-function of -wave interacting atoms is the root problem for any accurate numerical simulation. Here we apply the transcorrelated method, whe…

Einstein-de Haas Effect in a Dipolar Fermi Gas
Ulrich Ebling, Masahito Ueda
We show that an analogue to the classical Einstein-de Haas effect can appear in ultracold dipolar Fermi gases. The anisotropic nature of dipole-dipole interactions can lead to a tr…
