DMRG phase diagrams. The spin–spin correlator \(\left\langle {S_j^xS_k^x} \right\rangle\) at k − j = 50 along the leg of the strip with maximal correlations is shown in the first row, and the plaquette-plaquette correlator \(\left\langle {W_pW_{p\prime }} \right\rangle\) at p′ − p = 30 in the second as a function of Γ/K and h with Γ′ = −0.1. These are obtained in the two-leg honeycomb strip using DMRG with N = 200 and OBC. The field directions are constant in a given column, which are a θ = 0°, b θ = 5°, c θ = 10°, and d θ = 90° (\(\left[ {11\bar 2} \right]\) in-plane). Smooth curves fitted to peaks in either χh, or χΓ/K are drawn with red lines. The white arrow in the spin–spin correlators of a indicates the smooth connection from the intermediate phase to the pure Kitaev limit. The dashed green line at Γ/K = −0.325 indicates a representative slice where certain quantities are plotted in Fig. 5 for a θ = 5° tilted field
