The probability density plots for the states at zero energy corresponding to the parameter values (a) \(\xi =2.2\) and (b) \(\xi =2.5\). The system is in the SOTI phase and demonstrates the presence of corner modes shown by deep blue colour. The other relevant parameters are kept same as mentioned in Fig. 9. The Semenoff mass is kept 0.
