Calculations are performed on a discrete real-space lattice with periodic boundary conditions for the lamellar L(alpha), gyroid G, diamond D, and the Schwarz P phases for various twist angles. An isosurface analysis of the scalar order parameter reveals the structure of the surfactant monolayer at the interfaces between the oil-rich and water-rich regions. The curvature distributions show that the grain boundaries are minimal surfaces. The interfacial free energy per unit area is determined as a function of the twist angle for the G, D, P, and lamellar phases using two complementary approaches: the Ginzburg-Landau free-energy functional and a geometrical approach based on the curvature energy of a monolayer. For the L(alpha), G, and D phases the interfacial free energy per unit area is very small, has the same order of magnitude, and exhibits a nonmonotonic dependence on the twist angle. The P phase is found to be unstable with respect to the nucleation of grain boundaries. 000004228 536__ $$0G:(DE-Juel1)FUEK414$$2G:(DE-HGF)$$aKondensierte Materie$$cP54$$x0 000004228 588__ $$aDataset connected to Web of Science, Pubmed 000004228 650_7 $$2WoSType$$aJ 000004228 65320 $$2Author$$adiamond 000004228 65320 $$2Author$$afree energy 000004228 65320 $$2Author$$aGinzburg-Landau theory 000004228 65320 $$2Author$$aliquid crystals 000004228 65320 $$2Author$$amonolayers 000004228 65320 $$2Author$$asurface energy 000004228 65320 $$2Author$$asurfactants 000004228 65320 $$2Author$$atwist boundaries 000004228 7001_ $$0P:(DE-Juel1)130665$$aGompper, G.$$b1$$uFZJ 000004228 773__ $$0PERI:(DE-600)1473050-9$$a10.1063/1.3096987$$gVol. 130, p. 134712$$p134712$$q130<134712$$tThe @journal of chemical physics$$v130$$x0021-9606$$y2009 000004228 8567_ $$uhttp://dx.doi.org/10.1063/1.3096987 000004228 8564_ $$uhttps://juser.fz-juelich.de/record/4228/files/1.3096987.pdf$$yOpenAccess 000004228 8564_ $$uhttps://juser.fz-juelich.de/record/4228/files/1.3096987.gif?subformat=icon$$xicon$$yOpenAccess 000004228 8564_ $$uhttps://juser.fz-juelich.de/record/4228/files/1.3096987.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000004228 8564_ $$uhttps://juser.fz-juelich.de/record/4228/files/1.3096987.jpg?subformat=icon-700$$xicon-700$$yOpenAccess 000004228 909CO $$ooai:juser.fz-juelich.de:4228$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000004228 9131_ $$0G:(DE-Juel1)FUEK414$$bMaterie$$kP54$$lKondensierte Materie$$vKondensierte Materie$$x0$$zentfällt bis 2009 000004228 9141_ $$y2009 000004228 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000004228 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000004228 9201_ $$0I:(DE-Juel1)VDB782$$d31.12.2010$$gIFF$$kIFF-2$$lTheorie der Weichen Materie und Biophysik$$x0 000004228 9201_ $$0I:(DE-82)080012_20140620$$gJARA$$kJARA-HPC$$lJülich Aachen Research Alliance - High-Performance Computing$$x1 000004228 970__ $$aVDB:(DE-Juel1)110977 000004228 9801_ $$aFullTexts 000004228 980__ $$aVDB 000004228 980__ $$aConvertedRecord 000004228 980__ $$ajournal 000004228 980__ $$aI:(DE-Juel1)ICS-2-20110106 000004228 980__ $$aI:(DE-82)080012_20140620 000004228 980__ $$aUNRESTRICTED 000004228 981__ $$aI:(DE-Juel1)IBI-5-20200312 000004228 981__ $$aI:(DE-Juel1)IAS-2-20090406 000004228 981__ $$aI:(DE-Juel1)ICS-2-20110106 000004228 981__ $$aI:(DE-Juel1)VDB1346
