Quartic coupling and its effect on wetting behaviors in nematic liquid crystals |
Wetting diagram for paranematic wetting when t = 0.1500 is approached from below, in the parameter space of the surface potential: half cell thickness D versus the modulus of the quartic coupling strength − η for S s = −0.3, γ = 0.05, and h = 0.016 of the system: (a) without the quartic coupling and (b) with the quartic coupling. |
