An A*B copolymer chain and its labels.
A shift in the spinodal point between the SOP and VSOP model (α = 0.0001), where ΔχN is the difference in the spinodal point between the VSOP and the SOP models. Here, we use N = 600, a = 0.1 and the behavior is rather insensitive to the change in α under the α ≪ Γ JJ limit.
The metastable H* phase. The distance between the centers of the two neighboring cylinders is 4.7R g . In this figure, the cylinders are plotted with the isosurface ψ = 0.65. The helical amplitude and the pitch of helical cylinders are 0.5R g and 8.5R g , respectively.
The chiral interaction free energy density. The white circular curves are the A*-B interface (ψ = 0 isosurface). The superimposed gray plot indicates the chiral interaction free energy density in the H* structure. The dark region shows the strong chiral interaction near the A*-B interfaces.
The chain alignment strength. The interface ψ = 0 is at r = 1.47R g .
The angle between the chain alignment and the z axis. The interface ψ = 0 is at r = 1.47R g .
The zigzag H* phase. The cylinders have right-handed helical shape and sharp turns in a zigzag manner. The distance between the centers of the two neighboring cylinders is 4.5R g . The zigzag structure has a longer pitch P zigzag = 12.7R g , while the cylinder also has a shorter chiral helical pitch P* = 8R g . Note that the period of the zigzag undulation is just as twice as the helical pitch.
