Figure 5From: Propagation of quantum correlations after a quench in the Mott-insulator regime of the Bose-Hubbard modelAnisotropic propagation of correlations in 2D. Calculations for 30×30 sites. Coordinate dependences of the correlation function 〈 b ˆ μ 1 † b ˆ μ 2 〉 at different times after quench: tU=10 (a), 20 (b), 30 (c), 40 (d), 50 (e), 60 (f), 70 (g), 80 (h), 90 (i).Back to article page
