Breakdown of chiral edge modes in topological magnon insulators

J Habel, A Mook, J Willsher, J Knolle - Physical Review B, 2024 - APS
Topological magnon insulators (TMI) are ordered magnets supporting chiral edge magnon
excitations. These edge states are envisioned to serve as topologically protected information …

Corner-and sublattice-sensitive Majorana zero modes on the kagome lattice

M Kheirkhah, D Zhu, J Maciejko, Z Yan - Physical Review B, 2022 - APS
In a first-order topological phase with sublattice degrees of freedom, a change in the
boundary sublattice termination has no effect on the existence of gapless boundary states in …

Magnons, magnon bound pairs, and their hybrid spin-multipolar topology

A Mook, R Hoyer, J Klinovaja, D Loss - Physical Review B, 2023 - APS
We consider quantum condensed matter systems without particle-number conservation.
Since the particle number is not a good quantum number, states belonging to different …
