Weyl Magnons in the Non-Coplanar Antiferromagnet MnTe
Ahmed E. Fahmy, Archibald J. Williams, Yufei Li +9
Using a combination of band representation analysis, inelastic neutron scattering (INS), magneto-Raman spectroscopy measurements, and linear spin wave theory, we establish that the…
Quantum Sensing of Broadband Spin Dynamics and Magnon Transport in Antiferromagnets
Alex Lee Melendez, Shekhar Das, Francisco Ayala Rodriguez +8
Optical detection of magnetic resonance using quantum spin sensors (QSS) provides a spatially local and sensitive technique to probe spin dynamics in magnets. However, its utility…
High-throughput search for topological magnon materials
Mohammed J. Karaki, Ahmed E. Fahmy, Archibald J. Williams +3
Topological magnons give rise to possibilities for engineering novel spintronics devices with critical applications in quantum information and computation, due to its symmetry-prot…
New three-dimensional dispersion in the type-II Dirac semimetals PtTe and PdTe revealed through Angle Resolved Photoemission Spectroscopy
Ivan Pelayo, Derek Bergner, Archibald J. Williams +12
PtTe and PdTe are among the first transition metal dichalcogenides that were predicted to host type-II Dirac fermions, exotic particles prohibited in free space. These mate…
