Probing the Majorana bound states in a hybrid nanowire double-quantum-dot system by scanning tunneling microscopy |
Spectral functions A1(ω) and A2(ω) varying with ω for different values of coupling strength between the STM tip and DQ-2 γ2. In the calculations, we choose λ2 = 0.1, and other parameters are the same as those in Fig. |
