摘要:

从理论上研究了涡核周围的局域态密度,并讨论了在涡核中心附近产生的奇频率Cooper对。我们发现了一个强大的零能量峰的LDOS在涡旋核心的手征p波超导体起源于一个奇数ω s波对振幅。我们建议如何区分自旋三重态配对对称性和空间手性域结构的扫描隧道光谱通过奇Ω对振幅内的涡核。

英文摘要:

The local density of states (LDOS) around a vortex core is studied theoretically in terms of the odd-frequency (odd-omega) Cooper pairing induced around the center of the vortex core. We find a robust zero-energy peak in the LDOS at a vortex core in a chiral p-wave superconductor originating from an odd-omega s-wave pair amplitude. We suggest how to discriminate a spin-triplet pairing symmetry and spatial chiral-domain structure by scanning tunneling spectroscopy via odd-omega pair amplitudes inside vortex cores.
