Wavevector Scaling, Surface Critical Behavior, and Wetting in the 2-d, 3-State Chiral Clock Model

The controversial 2-d, 3-state chiral Ports model is studied using transfer matrix finite size scaling. At A =0, we find dqN/dA ocN -4/5, where q is the "wavevector," A the chiral field, and N the strip width (N=4-10). The result is consistent with den Nijs's crossover exponent q~ = 1/6. With surface fields on the infinite free boundaries, exponents associated with bulk magnetization Yu, surface magnetization y~, and surface susceptibility % are computed vs. A; results are similar for z] I] or • to the infinite direction. Preliminary results are given for the bulk specific heat critical amplitudes, to test the universality of amplitude ratios. The interface wetting line is located for 0_<A _< 1/4 using simple transfer matrix calculations of surface tensions in the solid-on-solid approximation. Overhangs or bubbles seem relatively unimportant at all temperatures.
