Quantum Geometric Quadrupole of Cooper Pairs
Wenqin Chen, Kaijie Yang, Ting Cao +3
The size of Cooper pairs defines a fundamental length scale of superconductivity, conventionally set by band dispersion and the superconducting gap. This picture breaks down in fla…

Quantum oscillation and topology change of the uncondensed Landau Fermi surface in superconducting CeCoIn5
Sangyun Lee, Duk. Y. Kim, Andrew J. Woods +5
Metals typically have multiple Fermi surface sheets, and when they enter the superconducting state, some electrons on these sheets may remain uncondensed, or their superconducting…
