Rolling Two-Dimensional Collinear Magnets into Chiral Nanotubes with -Wave Magnetism
Zhejunyu Jin, Robin R. Neumann, Rodrigo Jaeschke-Ubiergo +2
-wave magnets are noncollinear compensated magnetic systems that exhibit nonrelativistic antisymmetric spin splitting in momentum space. Their odd-parity spin symmetry enables u…
Nonlinear Magnon Magnetic Moment Transport in Triangular-Lattice f-Wave Antialtermagnets
Volodymyr P. Kravchuk, Kostiantyn V. Yershov, Bastián Pradenas +7
We study the spin excitations in the frustrated coplanar 120-degree ground state of the triangular-lattice Heisenberg antiferromagnet and demonstrate that they carry a magnetic mom…
Odd-Parity-Wave Magnons and Nonrelativistic Thermal Edelstein Effect
Robin R. Neumann, Rodrigo Jaeschke-Ubiergo, Ricardo Zarzuela +3
Odd-parity-wave magnets are noncollinear compensated magnets with spin-split band structure in the absence of spin-orbit coupling and dipolar interactions. In contrast to altermagn…
D-Wave Phonon Angular Momentum Texture in Altermagnets by Magnon-Phonon Hybridization
Hannah Bendin, Alexander Mook, Ingrid Mertig +1
In altermagnets, the magnon bands are anisotropically spin-split in reciprocal space without relativistic or dipolar spin-spin interactions. In this work, we theoretically study ma…
Large Thermal Hall Effect in MnPS
Mohamed Nawwar, Robin R. Neumann, Jiamin Wen +3
Recent studies have demonstrated that the thermal Hall effect can originate from magnons (magnon Hall effect), phonons (phonon Hall effect), or their combination (magnon-polaron Ha…
Sign Changes in Heat, Spin, and Orbital Magnon Transport Coefficients in Kitaev Ferromagnets
Yannick Höpfner, Ingrid Mertig, Robin R. Neumann
Both Kitaev and Dzyaloshinskii-Moriya interactions (DMI) are known to promote intrinsic contributions to the magnon Hall effects such as the thermal Hall and the spin Nernst effect…
