Spin Susceptibility of the Topological Superconductor UPt3 from Polarized Neutron Diffraction

W. J. Gannon, W. P. Halperin, M. R. Eskildsen +4

Experiment and theory indicate that UPt3 is a topological superconductor in an odd-parity state, based in part from temperature independence of the NMR Knight shift. However, quasi…
