Hello everyone. I am applying the spin orbit coupling to the honeycomb lattice but there are three different kind of hopping and I am writing this sys[lat.shape(shape, (2.46, 0))] =onsite sys[kwant.builder.HoppingKind((0, 0), A,B )]= -t * s_0 - 1j * alpha * s_y sys[kwant.builder.HoppingKind((0,1), A,B )] = -t * s_0 + 1j * alpha * s_x sys[kwant.builder.HoppingKind((-1,1), A,B )] = -t * s_0 + 1j * alpha * s_x But this is not right .What should I write in place of this.? please help me thank yo u in advance
