Transitions and Relaxations
TL;DR: The transition and relaxation processes in polymers are considered in this article, and recent progress and approaches toward both a phenomenological description and a theoretical understanding of its combined kinetic-thermodynamic character are outlined.
Journal ArticleDOI
Phase behavior and dynamics of a cholesteric liquid crystal
TL;DR: The synthesis, equation of state, phase diagram, and dielectric relaxation properties are reported for a new liquid crystal, 4(')-butyl-4-(2-methylbutoxy)azoxybenzene (4ABO5*), which exhibits a cholesteric phase at ambient temperature.

Tracking the time evolution of soft matter systems via topological structural heterogeneity
Ingrid Membrillo Solis,Tetiana Orlova,Karolina Bednarska,Piotr Lesiak,Tomasz R. Wolinski,Giampaolo D'Alessandro,Jacek Brodzki,Malgosia Kaczmarek +7 more
TL;DR: In this article , structural heterogeneity is used to characterize the dynamical behavior of semi-ordered soft-matter systems at a mesoscopic level and track their time-evolution, ultimately detecting the order-disorder transition at the microscopic scale.

Thermodynamics of the photoferroelectric effect in smectic-C* liquid crystals
Arne Langhoff,Frank Giesselmann +1 more
TL;DR: In this paper, a general thermodynamic description of the photoferroelectric effect, where the spontaneous polarization of a ferroelectric material is changed by interaction with light, is proposed.
Journal ArticleDOI
Orientational correlations in two-dimensional liquid crystals studied by molecular dynamics simulation.
TL;DR: The relation between the molecular interaction and the orientational correlation calculated for the 2D LC system offers much information not only about the2D LCs but also on the bulk system.

Self-Consistent Equations Including Exchange and Correlation Effects
Walter Kohn,L. J. Sham +1 more
TL;DR: In this paper, the Hartree and Hartree-Fock equations are applied to a uniform electron gas, where the exchange and correlation portions of the chemical potential of the gas are used as additional effective potentials.

Inhomogeneous Electron Gas
P. C. Hohenberg,Walter Kohn +1 more
TL;DR: In this article, the ground state of an interacting electron gas in an external potential was investigated and it was proved that there exists a universal functional of the density, called F[n(mathrm{r})], independent of the potential of the electron gas.
Book
Density-functional theory of atoms and molecules
TL;DR: In this paper, a review of current studies in density functional theory and density matrix functional theory is presented, with special attention to the possible applications within chemistry, including the concept of an atom in a molecule, calculation of electronegativities from the Xα method, pressure, Gibbs-Duhem equation, Maxwell relations and stability conditions.
