Isotropic phase of nematics in porous media (in English)
Abstract
We study the effect of random porous matrices on the isotropic- nematic phase transition. Sufficiently close to the cleaning temperature, both random field and thermal fluctuations are important as disordering agents. A novel random field fixed point of renormalization group equation was found that controls the transition from isotropic to the replica symmetric phase. Explicit evaluation of the exponents in d = 6 – ε dimensions yields to a dimensional reduction and three-exponent scaling.
