New models for Rydberg tweezer arrays: from doped quantum magnets to lattice gauge theories.

Large-scale quantum simulations of spin models in Rydberg tweezer arrays have unlocked new possibilities for exploring strongly correlated systems, offering advantages such as flexible geometries, single-site state preparation, and high data rates. In this talk, I will show how we can extend the toolbox of Rydberg tweezer arrays to realize new classes of Hamiltonians: First, I present a recent experimental realization of a doped quantum antiferromagnet with next-nearest neighbour tunnelings t' and hard-core bosonic holes using a Rydberg tweezer platform. We utilize coherent dynamics between three Rydberg levels, encoding spins and holes, to implement a tunable bosonic t-J-V model allowing us to study previously inaccessible parameter regimes. In this regime, J << t, we study phase separation using a dynamical protocol. Second, I will propose a scheme to stabilize an emergent Z2 lattice gauge structure in (2+1)D tweezer arrays. By deliberately driving the system far-from-equilibrium, we numerically examine the breakdown of gauge symmetry. We argue that the thermalization dynamics is captured by a universal hydrodynamic description. Together, these results illustrate how programmable quantum simulators can be pushed beyond traditional spin models to access richer many-body dynamics.
