It is now generally accepted that even low amounts of quenched disorder disrupt long-range
order in anisotropic systems with continuous symmetry. However, very little is known on the …

We considered general mechanisms enabling the stabilization of localized assemblies of
topological defects (TDs). There is growing evidence that physical fields represent …

We study the effect of random porous matrices on the ordering in nematic liquid crystals. The
randomness destroys orientational long-range order and drives the liquid crystal into a glass …

We review the theoretical research on the influence of disorder on structure and phase
behavior of condensed matter system exhibiting continuous symmetry breaking focusing on …

We theoretically study the generic mechanisms that could establish critical behavior in
nematic liquid crystals (NLCs). The corresponding free energy density terms should exhibit …

Glassy liquid crystalline systems are expected to show significant history-dependent effects.
Two model glassy systems are the RAN and SSS (sprinkled silica spin) lattice models. The …

The high-resolution calorimetric study was carried out on octylcyanobiphenyl liquid crystal
(LC) confined to various controlled-pore glass (CPG) matrices with silane-treated surface …

A detailed x-ray scattering and high-resolution ac calorimetric study has been carried out
near the smectic-A to chiral smectic-C phase transition of liquid-crystal compounds 4-(2 …

We consider the influence of different nanoparticles or micrometre-scale colloidal objects,
which we commonly refer to as particles, on liquid crystalline (LC) orientational order in …

Abstract Extensive Monte Carlo simulations are used to investigate the low-temperature
properties of the random anisotropy Heisenberg model, which describes the magnetic …
