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…
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…
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…
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…
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-…
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…
