- Abstract summary: We theoretically investigate the properties of two interacting ultracold highly magnetic atoms trapped in a one-dimensional harmonic potential.
We show the role of inability and symmetries in the dynamics by studying the time evolution of the observables.
The presented model may depict the on-site interaction of the extended Hubbard models, therefore giving a better understanding of the fundamental building block of the respective many-body quantum simulators.

- Abstract: We theoretically investigate the properties of two interacting ultracold
highly magnetic atoms trapped in a one-dimensional harmonic potential. The
atoms interact via an anisotropic long-range dipole-dipole interaction, which
in one dimension effectively can be modeled by the contact interaction. We
investigate the interplay of the external magnetic field, the spin-spin
interaction, and the trapping potential and how they affect the magnetization
of the system. We show the role of indistinguishability and symmetries in the
dynamics by studying the time evolution of the observables that could be
measured experimentally. The presented model may depict the on-site interaction
of the extended Hubbard models, therefore giving a better understanding of the
fundamental building block of the respective many-body quantum simulators.
