-wave magnet and hedgehog-type Berry curvature in helimagnetic MnAu
Hogyun Jeong, Sangyun Lee, Junhee Shin +4
Recently discovered altermagnetism in collinear compensated magnets shows even-parity spin texture in momentum space. Beyond the collinear spin ordering, unique odd-parity spin tex…
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…
Anomalous Mean-Squared Displacement in Quantum Active Matter from a Wigner Phase-Space Framework
Sangyun Lee, Yehor Tuchkov, Alexander P. Antonov +4
Active matter is driven out of equilibrium by a local influx of energy. While classical active matter has been extensively studied, the extension of active matter concepts to quant…
Development of a Capacitance Measurement for Pulsed Magnetic Fields
William K. Peria, Shengzhi Zhang, Sangyun Lee +4
Capacitance measurements are crucial for probing the electrical properties of materials. In this study, we develop and implement a capacitance measurement technique optimized for p…
Quantum Order by Disorder: A Key to Understanding the Magnetic Phases of BaCo(AsO)
Sangyun Lee, Shengzhi Zhang, S. M. Thomas +6
BaCo(AsO) (BCAO), a honeycomb cobaltate, is considered a promising candidate for materials displaying the Kitaev quantum spin liquid state. This assumption is based on…
Spectrum and low-temperature bulk properties of triangular quantum spin liquid candidate NaYbSe
A. O. Scheie, Minseong Lee, Kevin Wang +18
We report neutron scattering, pressure-dependent AC calorimetry, and AC magnetic susceptibility measurements of triangular lattice NaYbSe. We observe a continuum of scattering,…
Out-of-plane magnetic phase diagram of Kitaev quantum spin liquid candidate Na2Co2TeO6
Shengzhi Zhang, Sangyun Lee, Eric Brosha +4
We have investigated the magnetic properties and mapped out the phase diagram of the honeycomb magnet Na2Co2TeO6 with Co 3d7 in out-of-plane magnetic fields. This material has prev…
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…
