Configurational entropy of generalized sine–Gordon-type models

نویسندگان

چکیده

A family of deformed models the sine–Gordon-type can be generated by twisting sine–Gordon model. As a particular case, 3-sine–Gordon model is here addressed, whose differential configurational entropy and complexity three topological sectors are discussed using two complementary approaches. Stability aspects also discussed.

Configurational Entropy Revisited

1548 Journal of Chemical Education • Vol. 84 No. 9 September 2007 • www.JCE.DivCHED.org Entropy change is categorized in some prominent general chemistry textbooks as being either positional (configurational) or thermal. Positional entropy focuses on the number of positions in space that can be occupied by the molecules of a system. Then, to the extent that more positions exist after a process ...

Configurational entropy of hard spheres

We numerically calculate the configurational entropy Sconf of a binary mixture of hard spheres, by using a perturbed Hamiltonian method trapping the system inside a given state, which requires less assumptions than the previous methods [R.J. Speedy, Mol. Phys. 95, 169 (1998)]. We find that Sconf is a decreasing function of packing fraction φ and extrapolates to zero at the Kauzmann packing frac...

Configurational Entropy in Chiral Solutions - Negative Entropy of Solvent Envelopes

A homogeneous solution of a chiral substance is acquired with an overall asymmetry which is expressed by a specific rotation of a linearly polarized light. Such a solution, despite being at a complete equilibrium, stores configurational entropy in a form of negative entropy which can be nullified by mixing with a solution of the opposite enantiomer. This abundant, yet quite a specific case of i...

A Probabilistic Description of the Configurational Entropy

This work presents a formalism to calculate the configurational entropy of mixing based on the identification of non-interacting atomic complexes in the mixture and the calculation of their respective probabilities, instead of computing the number of atomic configurations in a lattice. The methodology is applied in order to develop a general analytical expression for the configurational entropy...
