Entropy microcanonical configurational

The lattice cluster theory (LCT) for glass formation in polymers focuses on the evaluation of the system s configurational entropy Sc T). Following Gibbs-DiMarzio theory [47, 60], Sc is defined in terms of the logarithm of the microcanonical ensemble (fixed N, V, and U) density of states 0( 7),... [Pg.143]

The configurational entropy per lattice site Sc, is related to the total (microcanonical) entropy Sc as... [Pg.143]

The configurational entropy term. Sc, is determined in the microcanonical formalism according to Boltzmann ... [Pg.334]

Suppose (9,11) holds at Iq- Then, for instance, using a microcanonical ensemble, where A = —TS, (i.e., only configurational entropies are used)... [Pg.99]

An alternate method of considering configurational entropy factors is through the Fourier integral representation of the microcanonical distribution described earlier. We will show how that formalism can be applied to a two-component, period-two DNA molecule as well as the one-component DNA molecule. [Pg.170]

In case of a continuous system, the number of states gE is replaced by the density of states g E), i.e., the number of states per energy. Since a microcanonical energetic macrostate is defined by the ensemble of system configurations (or conformations) with energies E — Ais/2 < E < E + i Ejl, the number of states in this ensemble is given by gE = g E)AE. The correct Boltzmann entropy formula would therefore read pE- -AE/2... [Pg.39]
