Quantum geometric origins of the orbital degrees of freedom of hybrid bosonic quasiparticles in magnetic systems
D. Quang To, Dai Q. Ho, Joshua M. O. Zide +5
The orbital degree of freedom has recently attracted significant attention due to the novel phenomena it enables in condensed matter systems. However, the interpretation of the orb…
Probing Magnetic Properties of RuO Heterostructures Through the Ferromagnetic Layer
Frank M. Abel, Subhash Bhatt, Shelby S. Fields +20
RuO has been proposed as the prototypical altermagnetic material. However, several reports have recently questioned its intrinsic magnetic ordering, leading to conflicting fi…
Symmetry-breaking induced surface magnetization in non-magnetic RuO
Dai Q. Ho, D. Quang To, Ruiqi Hu +2
Altermagnetism is a newly identified phase of magnetism distinct from ferromagnetism and antiferromagnetism. RuO has been considered a prototypical metallic altermagnet with a…
Tunable magnon band topology and magnon orbital Nernst effect in noncollinear antiferromagnets
D. Quang To, Dai Q. Ho, Joshua M. O. Zide +5
We theoretically investigate the intrinsic magnon orbital Nernst effect (ONE) in noncollinear antiferromagnets with Kagomé spin systems. Our analysis reveals that an externally ap…
Weyl semimetal phases and intrinsic spin-Hall conductivity in SbAs ordered alloys
Muhammad Zubair, Dai Q. Ho, Duy Quang To +2
Using density functional theory calculations we investigated possible Weyl semimetal (WSM) phases in antimony arsenide ordered alloys Sb1-xAsx (x=0, 1/6, 1/3, 1/2, 2/3, 5/6, 1). We…
Electric polarization induced by magnons and magnon Nernst effects
D. Quang To, Federico Garcia-Gaitan, Yafei Ren +5
Magnons offer a promising path toward energy-efficient information transmission and the development of next-generation classical and quantum computing technologies. However, method…
