(a) The illustration of s-wave pairing SC with Rashba SO coupling. (b) The particle density distribution of two zero modes around the two vortices for the case of u = −4ts, λ = 0.5ts, h = 0.8ts, Δ = 0.5ts. (c) The energy splitting δE as a function of the spacial distance of the two vortices D for the case of u = −4ts, λ = 0.5ts, h = 0.8ts, Δ = 0.5ts. a is the lattice constant.
