- Abstract summary: 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.
We first benchmark the Hamiltonian engineering for two atoms, and then demonstrate the freezing of the magnetization on an initially magnetized 2D array.

- Abstract: 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 magnetization on an initially
magnetized 2D array. Finally, we explore the dynamics of 1D domain wall systems
with both periodic and open boundary conditions. We systematically compare our
data with numerical simulations and assess the residual limitations of the
technique as well as routes for improvements. The geometrical versatility of
the platform, combined with the flexibility of the simulated Hamiltonians,
opens exciting prospects in the field of quantum simulation, quantum
information processing and quantum sensing.
