| Popis: | An ultrathin superconducting bilayer creates a coreless fractional vortex when only the second layer has a hole. The quantization is broken by the hole, and the normal core disappears. The magnetic flux is no longer confined near the normal core, and its density profile around the hole becomes similar to that of a cr\`eme caramel; the divergence of the magnetic flux density is truncated around the center. We propose basic design of a practical device to realize a coreless fractional vortex. Comment: 15 pages, 5 figures, The fourth version of the submission and the final update for arXiv. After this revision, the title is changed two times in a review process. In the first change, the title was "A vortex in a superconducting bilayer where one layer has a hole". The final title is "An unconventional vortex state in a superconducting bilayer where one layer has a hole" |
