Abstract The controversial 2-d, 3-state chiral Potts model is studied using transfer matrix finite size scaling. at Δ=0, we find dq N/dΔ∝N −4/5, whereq is the “wavevector”, Δ the chiral field, andN the strip width (N=4−10). The result is consistent with den Nijs's crossover exponent ϕ=1/6. With surface fields on the infinite free boundaries, exponents associated with bulk magnetizationy H, surface magnetizationy′ H, and surface susceptibility χ are computed vs. Δ; results are similar for $$\hat \Delta$$ ‖ 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≦Δ≦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.
