KW - Landau–Brazovskii model, Cylinder-Gyroid interface, saddle dynamics, transition state, transition pathway.
AB - <p style="text-align: justify;">When two distinct ordered phases contact, the interface may exhibit rich
and fascinating structures. Focusing on the Cylinder-Gyroid interface system, transition pathways connecting various interface morphologies are studied armed with the
Landau–Brazovskii model. Specifically, minimum energy paths are obtained by computing transition states with the saddle dynamics. We present four primary transition
pathways connecting different local minima, representing four different mechanisms
of the formation of the Cylinder-Gyroid interface. The connection of Cylinder and Gyroid can be either direct or indirect via Fddd with three different orientations. Under
different displacements, each of the four pathways may have the lowest energy.</p>
