| 英文摘要 | In this letter we construct a superconductor-Kitaev quantum spin liquid (QSL)-metal/semimetal tunnelling junction. By the tunnelling current, conductance, and d2I/dV2, we investigate the spin dynamics of the Kitaev QSL. We show that the d2I/dV2 of the tunneling current has three characteristics: the spectral gap at 0.26K, the positions of peak and dip at omega approximate to 0.5K and 2.26K, respectively, except for an energy shift of superconducting gap Delta = 0.5K. These characteristics are the same as the spin correlations function of the Kitaev QSL. These results show that the tunnelling junction method could be a powerful tool in revealing the exotic spin excitation properties of the QSL materials. |
