Visualizing Pair-breaking Scattering Interference in Bulk FeSe
Matthew Toole, Nileema Sharma, James McKenzie +3
Spatially periodic modulations of the superconducting gap have been recently reported in diverse materials and are often attributed to pair density wave order. An alternative mecha…
Odd-Parity Quasiparticle Interference in the Superconductive Surface State of UTe2
Shuqiu Wang, Kuanysh Zhussupbekov, Joseph P. Carroll +13
Although no known material exhibits intrinsic topological superconductivity, wherein spin-triplet odd-parity electron pairing occurs, UTe2 is now the leading representative of this…
Observation of Persistent Zero Modes and Superconducting Vortex Doublets in UTe
Nileema Sharma, Matthew Toole, James McKenzie +5
Superconducting vortices can reveal electron pairing details and nucleate topologically protected states. Yet, vortices of bulk spin-triplet superconductors have never been visuali…
Pair Wavefunction Symmetry in UTe2 from Zero-Energy Surface State Visualization
Qiangqiang Gu, Shuqiu Wang, Joseph P. Carroll +9
Although nodal spin-triplet topological superconductivity appears probable in UTe2, its superconductive order-parameter remains unestablished. In theory, a distinctive ident…
