Microscopic properties of fractional vortices and domain walls in three-band superconductors
Igor Timoshuk, Egor Babaev
Several experimental observations of objects carrying fractional flux quanta in superconductors were recently reported. Here, we provide microscopic solutions for vortices carrying…
Borromean supercounterfluids at finite temperatures
Alexandru Golic, Igor Timoshuk, Egor Babaev +1
While the properties of standard (single-component) superfluids are well understood, principal differences arise in a special type of multicomponent systems -- the so-called Borrom…
Observation of single-quantum vortex splitting in the BaKFeAs 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…
Microscopic solutions for vortex clustering in two-band type-1.5 superconductors
Igor Timoshuk, Egor Babaev
Two-band superconductors exhibit a distinct phase characterized by two correlation lengths, one smaller and the other larger than the magnetic field penetration length. This regime…
