“…CN = ±6, ±5, ±4, ±3, ±2, ±1) appearing and the TSC phase regions with CNs = 3 and −2 start to shrink when p A1 is greater than 0.14. The CN displays a sensitive dependence on V z and µ and distributes irregularly between CN = 3 and CN = −2 phases due to long-range pairing, which has also been observed in previous studies [19,20,22,24,[26][27][28][29]. It is notably that the sensitive non-zero CNs appear even under V z = 0 when p A1 is greater than or equal to 0.16 (see figures 2(c)-(f), 3 and 4), suggesting that there may be more intrinsic superconductors (e.g.…”

“…However, there are non-zero energy edge states inherited from the topological insulator in TSCs, affecting CNs and resulting in the mismatch [30]. Therefore, CN can predict the number of TESs crossing the E F but cannot predict the number of zero-energy Majorana edge states [19]. The closure and opening of bulk band-gap can lead to a topological phase transition [29], while the narrowing and widening of the bulk band-gap can also affect whether the TESs remain clean.…”
