    "abstract": "Langmuir monolayers are modeled as systems of short chains, which are\nconfined to a planar surface at one end, but free to move within the plane. The\nphase behavior is calculated in a mean field approximation, which combines the\nself consistent field method with elements of classical density functional\ntheory. It is shown that phases with tilt order are unstable in systems of\nstiff chains, but can be stabilized by chain conformational entropy in systems\nof sufficiently flexible chains. The chain entropy is also responsible for the\nappearance of an additional untilted phase, the liquid expanded phase. The\nregion of stability of the different phases is discussed, and their microscopic\nstructure is analyzed in some detail.",
