Fig. 10: Numerical result of exceptional points.

a Exceptional points touch the dBIS (black line) for type-I transition. The noise strength is wx = 0.1t0, wy = 0.05t0, wz = 0.45t0. b Exceptional point (white dot) emerges at the charge momentum (green dot) at k = 0, to which the dBIS connects for type-II transition. The noise strength is wx = 1.6t0, wy = 0t0, wz = 0.8t0.
