Microscopic Theory of the Acoustic Faraday Effect in Spin-Orbit Coupled Magnets
Antoine Matar, Haoting Xu, Hae-Young Kee
The acoustic Faraday effect probes phonon Hall viscosity through the rotation of transverse acoustic polarization, conventionally interpreted in terms of circular birefringence. We…
Emergent low-energy thermodynamics and universal scaling in -RuCl
A. Khansili, B. J. Ramshaw, A. Bangura +6
Quantum spin liquids are exotic states of matter in which strongly interacting spins remain disordered down to zero temperature and host fractionalized excitations. This has motiva…
Evolution from Kitaev to XXZ spin chains via distortion: Application to BaCoVO
Philip Richard, Mandev Bhullar, Hae-Young Kee
BaCoVO is a prototypical spin-orbit-coupled Ising-chain antiferromagnet that provides a unique platform for studying field-induced quantum magnetism. Under a transverse…
Symmetry-Enforced Pair-Density Wave and Chiral Interband Superconductivity in Strongly Correlated Kagome Systems
Alex Friedlan, Hae-Young Kee
The pair-density wave (PDW) state, characterized by Cooper pairing at finite momentum, is a long-sought superconducting phase whose possible realization in Kagome metals is particu…
Understanding Anomalous Magnetothermal Transport via Disentangling Shear and Compression Phonons
Haoting Xu, Antoine Matar, Hae-Young Kee
Magnetothermal transport in various frustrated magnets exhibits striking field-dependent anomalies that deviate from conventional magnon or phonon transport. To understand such ano…
Ferrichiral skyrmions with sublattice-resolved chirality in extended Kitaev model in triangular lattice
Bogeng Wen, Jiefu Cen, Hae-Young Kee
We study an extended Kitaev model on the triangular lattice in a limit where the symmetric off-diagonal bond-dependent and Heisenberg interactions together map onto an XXZ model, i…
Microscopic Theory Revealing Ising Criticality with Distinct Sublattice Orders in Pseudospin-1/2 Chain
Mandev Bhullar, Philip Richard, Hae-Young Kee
The one-dimensional transverse Ising model is a paradigmatic example of quantum criticality. In spin-orbit coupled systems, however, effective Ising interactions arise alongside bo…
Magnetically ordered yet topologically robust phases emerging in concurrent Kitaev spin liquids
Muhammad Akram, Aayush Vijayvargia, Hae-Young Kee +1
Spin-orbital generalizations of Kitaev model, such as Yao-Lee model, have attracted recent attention due to their enhanced stability of spin liquid phases against perturbations. Mo…
Field-Induced Ordered Phases in Anisotropic Spin-1/2 Kitaev Chains
Mandev Bhullar, Haoting Xu, Hae-Young Kee
Motivated by intense research on two-dimensional spin-1/2 Kitaev materials, Kitaev spin chains and ladders, though geometrically limited, have been studied for their numerical simp…
Kitaev Quantum Spin Liquids
Yuji Matsuda, Takasada Shibauchi, Hae-Young Kee
Quantum spin liquids (QSLs) represent exotic states of matter where quantum spins interact strongly yet evade long-range magnetic order down to absolute zero. Characterized by non-…
Emergence of quadrupolar order under magnetic field in double perovskites
Stashu Kozlowski, Derek Churchill, Hae-Young Kee
Motivated by the time-reversal symmetry breaking signal in muon spin relaxation below a transition temperature without accompanying noticeable magnetic Bragg peaks in Os dou…
Microscopic Roadmap to a Yao-Lee Spin-Orbital Liquid
Derek Churchill, Emily Z. Zhang, Hae-Young Kee
The exactly solvable spin-1/2 Kitaev model on a honeycomb lattice has drawn significant interest, as it offers a pathway to realizing the long-sought after quantum spin liquid. Bui…
Reviving Majorana zero modes in the spin-1/2 Kitaev ladder model

The one-dimensional -wave superconductor, characterized by boundary Majorana modes, has attracted significant interest owing to its potential application in topological quantum…
Transforming from Kitaev to Disguised Ising Chain: Application to CoNbO
Derek Churchill, Hae-Young Kee
For many years, CoNbO has served as an exemplar of the one-dimensional Ising model. However, recent experimental and theoretical analyses challenge its applicability to thi…
Finite-momentum and field-induced pairings in orbital-singlet spin-triplet superconductors
Jonathan Clepkens, Hae-Young Kee
Finite-momentum pairing in a Pauli-limited spin-singlet superconductor arises from the pair-breaking effects of an external Zeeman field, a mechanism which is not applicable in odd…
