Field-Induced Selective Spin Gap Closure and Quantum Criticality in BaNdZnS
Sangyun Lee, A. J. Woods, B. Billingsley +11
We report thermodynamic evidence for field-induced mode-selective quantum criticality in the layered rare-earth magnet BaNd2ZnS5 (BNZS). Below the Neel temperature TN = 2.9 K, spin…

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…
