Isotropic phase of nematics in porous media
B. M. Khasanov Department of Physics, Kazan State University, 420008 Kazan, Russia
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 $d=6-\varepsilon$ dimensions yields to a dimensional reduction and three-exponent scaling.
