Observation of single-quantum vortex splitting in the Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ superconductor

Q. Z. Zhou, B. R. Chen, B. K. Xiang +12

Since their theoretical discovery more than a half-century ago, vortices observed in bulk superconductors have carried a quantized value of magnetic flux determined only by fundame…

Direct observation of quantum vortex fractionalization in multiband superconductors

Yu Zheng, Quanxin Hu, Haijiao Ji +13

Magnetic field is expelled from a superconductor, unless it forms quantum vortices, consisting of a core singularity with current circulating around it. The London quantization con…

Ultrasound evidence for multicomponent superconducting order parameter in Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ with electron quadrupling phase

Chris Halcrow, Ilya Shipulin, Federico Caglieris +6

Experiments have pointed to the formation of the electron quadrupling condensate in Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ at $x \sim 0.8$ . The state spontaneously breaks time-reversal symmet…
