First-order and continuous Fréedericksz transitions in cholesteric liquid crystals.
The Fréedericksz transition in twist cells of cholesteric liquid crystals with a finite surface energy is considered. It is shown that this transition can be either of the second order or of the first order depending on the values of the Frank constants, pitch, surface energies, and the cell thickness. A simple criterion that determines the order of the phase transition is obtained. By numerica...
متن کاملSusceptibilities and Order Parameters of Nematic Liquid Crystals
The magnetic susceptibilities of MBBA, p-quinquephenyl, and the cyano-biphenyl compounds NCB where N ranges from 5 to 9 have been measured as a function of temperature in the nematic range. In the nematic range the susceptibility is anisotropic and AX = (x i , xL) should be proportional to the order parameter S. The coefficients of proportionality S/AX have been calculated using information ava...
متن کاملShort-Range Smectic Order in Bent-Core Nematic Liquid Crystals
Small angle X-ray diffraction from the uniaxial nematic phase of certain bent-core liquid crystals is shown to be consistent with the presence of molecular clusters possessing short-range tilted smectic (smectic-C) order. Persistence of these clusters throughout the nematic phase, and even into the isotropic state, likely accounts for the unusual macroscopic behavior previously reported in bent...
متن کاملOn the second order first zagreb index
Inspired by the chemical applications of higher-order connectivity index (or Randic index), we consider here the higher-order first Zagreb index of a molecular graph. In this paper, we study the linear regression analysis of the second order first Zagreb index with the entropy and acentric factor of an octane isomers. The linear model, based on the second order first Zag...
متن کاملSimultaneous first- and second-order percolation transitions in interdependent networks.
In a system of interdependent networks, an initial failure of nodes invokes a cascade of iterative failures that may lead to a total collapse of the whole system in the form of an abrupt first-order transition. When the fraction of initial failed nodes 1-p reaches criticality p = p(c), the abrupt collapse occurs by spontaneous cascading failures. At this stage, the giant component decreases slo...
