Yu-Shiba-Rusinov (YSR) 态是指在超导体中由磁性杂质引起的一种局部束缚态。这些态是由Yu、Shiba和Rusivov分别在20世纪60年代理论预测的,因此得名。 在s波kagome超导体中,YSR态的研究尤其重要,因为kagome晶格结构本身具有独特的几何特性和拓扑性质,这使得它在研究新颖的量子现象和新型超导态方面具有很大的潜力。 具...
通常，超导体上具有两大类缺陷态：磁性杂质诱导的具有自旋极化的Yu-Shiba-Rusinov (YSR)束缚态和磁场诱导的磁通涡旋内的Caroli-de-Gennes-Matricon (CdGM) 束缚态。2015年，殷嘉鑫等人在中国科学院物理研究所潘庶亨研究员和丁洪研究员的指导下利用极低温高分辨率STM在铁基超导体Fe1+x(Te, Se)中处于间隙位置的单个...
These channels are mixed by the spin-orbit coupling and, via the hybridization of the Yu-Shiba-Rusinov states at different sites of the chain, result in a multi-band structure for the chain. We obtain the topological phase diagram for such band structure. We identify the parameter regimes ...
Yu–Shiba–Rusinov (YSR) states1,2,3can be imaged in a direct manner by scanning-tunneling spectrocopy of magnetic adatoms on the surface of a superconductor4. Using superconducting tips, high-resolution bias spectroscopy of multiple sub-gap peaks reveals an impressive amount of atomistic details...
• Yu–Shiba–Rusinov states induced in an A15-compound superconductor. • Dependence of intragap states on the adsorption site of the single-atom magnetic impurity. • Three-dimensional character of scattering unveiled by strong damping of the spectral weight in spatially resolved spectroscopy. ...
topology, Yu–Shiba–Rusinov statesWhen magnetic atoms are inserted inside a superconductor, the superconducting order is locally depleted as a result of the antagonistic nature of magnetism and superconductivity1. Thereby, distinctive spectral features, known as Yu-Shiba-Rusinov states, appear inside ...

The strong coupling of a superconductor to a spinful quantum dot results in Yu–Shiba–Rusinov discrete subgap excitations. In isolation and at zero temperature, the excitations are sharp resonances. In transport experiments, however, they show as broad
A Yu-Shiba-Rusinov (YSR) state is a localized in-gap state induced by a magnetic impurity in a superconductor. Recent experiments used an STM tip to manipulate the exchange coupling between an Fe adatom and the {m FeTe}_{0.55}{m Se}_{0.45} F e T e 0.55 S e 0.45 {m FeTe}_{0.55...
Yu-Shiba-Rusinov states in phase-biased S-QD-S junctions We study the effects of a phase difference on Yu-Shiba-Rusinov (YSR) states in a spinful Coulomb-blockaded quantum dot contacted by a superconducting loop. In the limit where charging energy is larger than the superconducting gap, we...
