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.
