Phys. Rev. Lett. 55, 1771–1774 (1985)Monte Carlo study of the nematic–to–smectic-A transitionReceived 12 July 1985; published in the issue dated 21 October 1985 A Monte Carlo simulation of a lattice model of the nematic–to–smectic-A transition in three dimensions shows a continuous phase transition with the specific-heat exponent α≃0. The order-parameter correlation functions show anisotropic critical behavior in the nematic phase, where the behavior of the correlation functions in the superconducting gauge strongly indicates an isotropic critical point. Several features observed in experiments are qualitatively reproduced in the simulation. © 1985 The American Physical Society URL:
