In Fig. 4, the left panel shows the Brillouin zone of the brick-wall lattice. In order to clearly manifest the mapping from the brick-wall lattice model to the square lattice model, we first map the Brillouin zone of the brick-wall lattice into the reciprocal space of the square ...
Figure2bshows, by the white lines, the calculated dispersion using a tight-binding Hamiltonian that takes into account the nominal variation oft1(x) implemented in the lattice and an onsite energy offset Δ = 1.6tapplied to the leftmost and rightmost columns of micropillars in the lattice....
3b. For each phase, the real-space spin configuration and the reciprocal-space Bragg peak positions are shown. In the absence of J2 and J3, the system is in a spin-liquid phase characterized by a structureless SðQÞ (Fig. 3c) that is adiabatically connected to the Kitaev liquid ...
