We use the resonant dipole-dipole interaction between Rydberg atoms and a periodic external microwave field to engineer XXZ spin Hamiltonians with tunable anisotropies. The atoms are placed in 1D and 2D arrays of optical tweezers, allowing us to study iconic situations in spin physics, such as the implementation of the Heisenberg model in square arrays, and the study of spin transport in 1D. We first benchmark the Hamiltonian engineering for two atoms, and then demonstrate the freezing of the… Expand

Optical Control of the Resonant Dipole-Dipole Interaction between Rydberg Atoms.
TLDR
This work reports on the local control of the transition frequency of a spin 1/2 encoded in two Rydberg levels of an individual atom by applying a state-selective light shift using an addressing beam, and shows that after preparing an initial single spin excitation, it can freeze the dynamics at will with the addressing laser, while preserving the coherence of the system.

Realization of the Hofstadter Hamiltonian with ultracold atoms in optical lattices.
TLDR
It is shown that for two atomic spin states with opposite magnetic moments, the experimental implementation of an optical lattice that allows for the generation of large homogeneous and tunable artificial magnetic fields with ultracold atoms naturally realizes the time-reversal-symmetric Hamiltonian underlying the quantum spin Hall effect.

TLDR
The Berry curvature is engineered and measured in a simulated boron-nitride optical lattice filled with fermionic K atoms and the results pave the way to explore intriguing phases of matter with interactions in topological band structures. Expand
