(color online) The effect of vertical tilting ε_v on the tunneling dynamics for bosons initially configured as {a_n, b_n, c_n} = {1, 0, −1}e^{−n₂/2σ²} (the eigenstate for the case of ϕ = ε_v = 0), which is demonstrated by the space–time evolution of the norm density p_n(t) (the first row) and the corresponding evolution for bosons in single chain (a, b, and c chains) are depicted by |a_n(t)|² (the second row), |b_n(t)|² (the third row), and |c_n(t)|² (the fourth row), respectively.
