Signature of chiral superconducting order parameter evidenced in mesoscopic superconductors
Xiaoying Xu, Wei Qin, Yuelin Shen +4
Chiral superconductivity is a novel superconducting phase characterized by order parameters that break the time-reversal symmetry, endowing the state with a definite handedness. Un…
Unequivocal Determination of Spin-Triplet Superconductivity Using Composite Rings
Xiaoying Xu, Yufan Li, C. L. Chien
Phase-sensitive measurements on a composite ring made of a superconductor of interest connected by a known singlet -wave superconductor can unambiguously determine its pairing s…
Fractional Little-Parks effect observed in a topological superconductor
Yufan Li, Xiaoying Xu, Shu-Ping Lee +1
In superconductors, the condensation of Cooper pairs gives rise to fluxoid quantization in discrete units of . The denominator of is the signature of electron p…
Spin-triplet pairing state evidenced by half-quantum flux in a noncentrosymmetric superconductor
Xiaoying Xu, Yufan Li, C. -L. Chien
A prime category of superconducting materials in which to look for spin-triplet pairing and topological superconductivity are superconductors without inversion symmetry. It is pred…
Observation of Half-Quantum Flux in Unconventional Superconductor -BiPd
Yufan Li, Xiaoying Xu, C. L. Chien
We report the observation of half-integer magnetic flux quantization in mesoscopic rings of superconducting -BiPd thin films. The half-quantum fluxoid manifests itself as a…
Tuning the metal-insulator transition in manganite films through surface exchange coupling with magnetic nanodots
T. Z. Ward, Z. Gai, X. Y. Xu +3
In strongly correlated electronic systems, such as manganites, the global transport behavior depends sensitively on the spin ordering, whose alteration often requires a large exter…
