WebEdwards' self‐consistent field (SCF) theory of excluded volume follows upon introduction of the appropriate Markovian approximation into the lowest member of the hierarchy. The use of this approximation in the next member leads to a SCF theory which is almost identical to that which follows from Reiss' variational approach.

WebFeb 3, 2024 · In this unfortunate scenario, the orbital occupation number oscillates between two patterns, which prevents convergence. Typical signatures of this scenario include an oscillating SCF energy (with an amplitude of $10^{-4} \sim 1$ Hartree), and a clearly wrong occupation pattern printed at the end of the SCF calculation.

WebNov 14, 2016 · Self Consistent Field (SCF) theory serves as an efficient tool for studying mesoscale structure and thermodynamics of polymeric liquid crystals (LC). We investigate how some of the intrinsic approximations of SCF affect the description of the thermodynamics of polymeric LC, using a coarse-grained mo … WebDec 6, 2012 · A General SCF Theory.
