abstract = {<p style="text-align: justify;">We propose a general framework of computing interfacial structures between
two modulated phases. Specifically we propose to use a computational box
consisting of two half spaces, each occupied by a modulated phase with given position
and orientation. The boundary conditions and basis functions are chosen to be
commensurate with the bulk phases. We observe that the ordered nature of modulated
structures stabilizes the interface, which enables us to obtain optimal interfacial
structures by searching local minima of the free energy landscape. The framework is
applied to the Landau-Brazovskii model to investigate interfaces between modulated
phases with different relative positions and orientations. Several types of novel complex
interfacial structures emerge from the calculations.</p>},
