Quantum Chains: Untangling Interactions in Rydberg Atom Systems
![The study reveals that subtle deviations from a simplified [latex]\hat{H}_{PXQ}[/latex] Hamiltonian-attributable to longer-range interactions-manifest as measurable changes in the average classical number of excitations, leakage from the single dimer subspace, and the averaged Rydberg population difference, despite nearly identical dynamics predicted by both the simplified and full [latex]\hat{H}_{0}[/latex] Hamiltonians across a system of length ten.](https://arxiv.org/html/2601.15866v1/fig/Fig6_Ncl_single_excited_v1.png)
