Fig. 5: Exact diagonalization results for edge and vortex core Majorana modes.
a Pairing amplitudes for the f-wave order parameter on the simplified triangular lattice model with lattice constant a0. ΔN and ΔNN denote the nearest-neighbor and second-nearest-neighbor pairing amplitudes, respectively. b Spectral function A(qx, ω) evaluated at the edges and in the bulk of an infinite strip with width of L = 200 sites. ω is shown in units of t0. c Local density of states ρ(ω, r) computed on a hexagon-shaped sample with N = 3169 sites and a vortex located at its center. d Real-space probability distribution of zero-energy eigenstates \({{{\Psi }}}_{0}^{\pm }=({{{\Psi }}}_{0}\pm {{{\Psi }}}_{0}^{{\prime} })/\sqrt{2}\). The color bar indicates the normalized value of probability distribution to the maximum site amplitude for each state. In all panels parameters \(({\mu }_{0},{{{\Delta }}}_{N},{{{\Delta }}}_{NN})=(0.8{t}_{0},0.5{t}_{0},{{{\Delta }}}_{N}/3\sqrt{3})\) with t0 = − 0.01 eV were used.
