Extended Data Figure 1: A long-time partial revival in the long-range Ising model.
From: Non-local propagation of correlations in quantum systems with long-range interactions
a, Spatial correlations measured at long times after a global quench of an Ising model with α = 0.63. b, A small partial revival in correlation between sites 1 and 2 is evident, showing quantum coherence at long times. The black line shows the exact solution predicted from equation (4). Error bars, 1 s.d.
