Spin-resolved quantum gas microscopy of fermionic Mott insulators

ORAL

Abstract

Ultracold atoms in optical lattices are a versatile platform to study strongly correlated systems in which exotic states of matter appear due to the interplay between charge and magnetic order.

Here, we report on the study of lithium-6 Mott insulators in a frustrated triangular Hubbard system and rely on spin-spin correlations for thermometry [1].

We demonstrate the implementation of a spin-resolved imaging technique using a bilayer readout inspired by ref. [2], expanding observable quantities beyond singles density and spin-spin correlations.

We are planning to introduce non-local interactions in the frustrated triangular system using Rydberg-dressing, thereby implementing an extended triangular Hubbard model which is predicted to host a variety of exotic quantum phases.
