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…
Normal Fermi Surface in the Nodal Superconductor CeCoIn Revealed via Thermal Conductivity
Sangyun Lee, Duk Y. Kim, Priscila F. S. Rosa +5
The thermal conductivity of heavy-fermion superconductor CeCoIn was measured with a magnetic field rotating in the tetragonal a-b plane, with the heat current in the anti-nodal…
Anisotropic field-induced changes in the superconducting order parameter of UTe2
Sangyun Lee, Andrew J. Woods, P. F. S. Rosa +4
UTe2 is a newly discovered unconventional superconductor, where electron Cooper pairs combine into a spin-triplet ground state. Here we report the specific heat C(H,T) of a high-qu…
The magnitude of the magnetic exchange interaction in the heavy fermion antiferromagnet CeRhIn
Pinaki Das, S. -Z. Lin, N. J. Ghimire +7
We have used high-resolution neutron spectroscopy experiments to determine the complete spin wave spectrum of the heavy fermion antiferromagnet CeRhIn. The spin wave dispersion…
