The LDOS as a function of the energy (E|μ|) with surface impurities: (a)–(d) a surface charge impurity and (e)–(h) a surface magnetic impurity. The four columns from left to right correspond to no order parameters, A₁ order parameter, A₂ order parameter, and E order parameter, respectively. The broadening of each peak and the parameters choices for the orders if exist are the same as those in Fig. 2. The potential form of the charge or magnetic impurity is shown in Appendix F. The numbers on the vertical axes are again omitted.
