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…
Magnetic field-temperature phase diagram of spin-1/2 triangular lattice antiferromagnet KYbSe
Sangyun Lee, Andrew J. Woods, Minseong Lee +7
A quantum spin liquid (QSL) is a state of matter characterized by fractionalized quasiparticle excitations, quantum entanglement, and a lack of long-range magnetic order. However,…
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…
Non-linear magnons and exchange Hamiltonians of delafossite proximate quantum spin liquids
A. O. Scheie, Y. Kamiya, Hao Zhang +20
Quantum spin liquids (QSL) are theoretical states of matter with long-range entanglement and exotic quasiparticles. However, they generally elude quantitative theory, rendering the…
