Numerical solutions for large lattice in 2D. Calculations for 30×30 sites. Upper panel: Probabilities to have zero (red) and two (green) particles on a lattice site. Middle panel: b ˆ μ b ˆ μ + e 1 s , s=1,,29. Red line s= v max t, v max =3J. Lower panel: b ˆ μ b ˆ μ + ( e 1 + e 2 ) s , s=1,,29. Red line s= 2 v max t, v max =3J/ 2 . e 1 and e 2 are unit vectors along the lattice axes.
