Review on Crystallization Strategies for Polymer Single Crystals [PDF]
CrystalsPolymer physics has evolved significantly over the past century, transitioning from the early recognition of the chain structure of polymers to a mature field integrating principles from statistical mechanics, thermodynamics, and condensed matter physics.

Statistical mechanics of defects in polymer liquid crystals [PDF]
Journal de Physique II, 1992 We develop a continuum theory for the statistical mechanics of thermally activated point defects in the nematic and hexagonal phases of polymer liquid crystals. In the nematic phase, there are elementary splay defects (chain ends and hairpins), and in the hexagonal phase, there are both splay defects and twist defects.

Mechanical Proof of the Second Law of Thermodynamics Based on Volume Entropy [PDF]
, 2007 In a previous work (M. Campisi. Stud. Hist. Phil. M. P. 36 (2005) 275-290) we have addressed the mechanical foundations of equilibrium thermodynamics on the basis of the Generalized Helmholtz Theorem.

Granular Crystals: Controlling Mechanical Energy with Nonlinearity and Discreteness [PDF]
, 2011 The presence of structural discreteness and periodicity can affect the propagation of phonons, sound, and other mechanical waves. A fundamental property of many of the periodic structures and materials designed for this purpose is the presence of ...

Line-tension model for plasticity as the Gamma-limit of a nonlinear dislocation energy [PDF]
, 2012 In this paper we rigorously derive a line-tension model for plasticity as the Gamma-limit of a nonlinear mesoscopic dislocation energy, without resorting to the introduction of an ad hoc cut-off radius.

Statistical mechanics of crystal nuclei of hard spheres
The Journal of Chemical PhysicsIn the study of crystal nucleation via computer simulations, hard spheres are arguably the most extensively explored model system. Nonetheless, even in this simple model system, the complex thermodynamics of crystal nuclei can sometimes give rise to counterintuitive results, such as the recent observation that the pressure inside a critical nucleus is ...

Geometric variational problems of statistical mechanics and of combinatorics [PDF]
, 2000 10 pagesWe present the geometric solutions of the various extremal problems of statistical mechanics and combinatorics. Together with the Wulff construction, which predicts the shape of the crystals, we discuss the construction which exhibits the shape ...
