Dislocation-loop melting theory of phase diagrams with nematic regions surrounded by smectic regions
Abstract
We show that a dislocation-loop theory of the smectic-Anematic transition predicts the existence of both nematic regions surrounded by smectic regions and a smectic A1-Ad critical point in the phase diagram, in agreement with recent observations. Fluctuation-corrected mean-field theory leads to a remarkable topology for the isolated nematic region. © 1987 The American Physical Society.
