Topological Magnon-Plasmon Hybrids
Tomoki Hirosawa, Pieter M. Gunnink, Alexander Mook
We study magnon-plasmon coupling in effectively two-dimensional stacks of van der Waals layers in the context of the band structure topology. Invoking the quasiparticle approximati…

Vortex Crystals in Tetrahedral Antiferromagnets: Fractional Charges and Topological Magnons
Tomoki Hirosawa, Alexander Mook, Maria Azhar
We report the formation of a vortex crystal in the tetrahedral antiferromagnetic order on a triangular lattice. The noncoplanar tetrahedral state consists of four su…

Density Matrix Renormalization Group Study of Domain Wall Qubits
Guanxiong Qu, Ji Zou, Daniel Loss +1
Nanoscale topological spin textures in magnetic systems are emerging as promising candidates for scalable quantum architectures. Despite their potential as qubits, previous studies…
