The physics of liquid crystals
Part 1 Liquid crystals - main types and properties: introduction - what is a liquid crystal? the building blocks nematics and cholesterics smectics columnar phases more on long-, quasi-long and
Random anisotropy in amorphous ferromagnets
Random anisotropy is present in all amorphous magnetic materials, and depending on its strength, it can dramatically affect the magnetic behavior. We describe the effect of strong random anisotropy
Liquid crystal phase transitions in mixtures of rodlike and platelike molecules
Model calculations are presented which indicate that the character of the nematic‐isotropic phase transition can be continuously changed from first to second order and that a new biaxial liquid
Pretransition Effects in Nematic Liquid Crystals: Model Calculations
Abstract Calculations of the properties of some lattice models and continuum models of a hard rod liquid with and without attractive energies are presented. The theory is of the “molecular field”
Structural model for amorphous solid water
We construct two continuous random network models for amorphous solid water and compute their x‐ray and neutron diffraction properties. The results for one type of network accord well with
Lattice Model for Biaxial Liquid Crystals
The possibility that the repulsive interaction between platelike molecules might give rise to biaxial liquid crystal order is examined by considering a molecular‐field lattice model in which
Exact results for a three-dimensional alloy with site diagonal disorder: comparison with the coherent potential approximation
Densities of states and spectral functions are obtained for large (approx. 8000 atoms) three-dimensional alloy models with cell localized disorder and are compared with the single-site
