20-22.02.2024 - Workshop on Quantum Simulators of the Future: From Dynamical Gauge Fields to Lattice Gauge Theories | (smr 3922)

An ICTP Meeting This Workshop will gather world-leading groups that design, realize, and characterize a new generation of simulators with ultracold atoms and beyond. It will address novel quantum simulators of statistical gauge fields, dynamical lattices, and lattice gauge theory models (LGT), as well as connections to quantum computing and tensor network methods.

Non-ergodic dynamics in many-body interacting systems has recently attracted much interest. Polar lattice gases present, even in absence of disorder, an intriguing dynamics, which has been mostly discussed in the hard-core regime. We show that the dynamics of soft-core dipolar lattice bosons may be remarkably different. We find that contrary to hard-core dipoles, bosons tend to delocalize for large inter-site interaction strengths due to the crucial role played by interaction-induced hopping. Interestingly, the interplay between bare and interaction-induced tunneling may lead, near a lattice-depth-dependent value of the dipole strength, to an exact decoupling of the Hilbert space between ergodic states with at most singly-occupied sites, and the remaining strongly non-ergodic states. Our results highlight the key role that density-dependent hopping may play in future experiments on out-of-equilibrium systems with long-range interactions.
