dc.description.abstract | We have employed the density functional theory formalism to investigate the nematic–isotropic
capillary transitions of a nematogen confined by walls that favor antagonist orientations to the liquid
crystal molecules ~hybrid cell!. We analyze the behavior of the capillary transition as a function of
the fluid–substrate interactions and the pore width. In addition to the usual capillary transition
between isotropiclike to nematiclike states, we find that this transition can be suppressed when one
substrate is wet by the isotropic phase and the other by the nematic phase. Under this condition the
system presents interfacelike states which allow us to continuously transform the nematiclike phase
to the isotropiclike phase without undergoing a sharp phase transition. Two different mechanisms for
the disappearance of the capillary transition are identified. When the director of the nematiclike state
is homogeneously planar-anchored with respect to the substrates, the capillary transition ends up in
a critical point. This scenario is analogous to the observed in Ising models when confined in slit
pores with opposing surface fields which have critical wetting transitions. When the nematiclike
state has a linearly distorted director field, the capillary transition continuously transforms in a
transition between two nematiclike states | es |
