Topological Magnons on the Ferromagnetic Zigzag Lattice
Skandan Subramanian, Tom Berlijn, Lucas Lindsay +2
Motivated by the experimental identification of magnetic compounds consisting of zigzag chains, we analyze the band structure topology of magnons in ferromagnets on a zigzag lattic…
Collective nature of phonon energies in solids beyond harmonic oscillators
Jaeyun Moon, Leo Zella, Lucas Lindsay
Phonon quasi-particles have been monumental in microscopically understanding thermodynamics and transport properties in condensed matter for decades. Phonons have one-to-one corres…
Dynamics of nonequilibrium magnons in gapped Heisenberg antiferromagnets
Chengyun Hua, Lucas Lindsay, Yuya Shinohara +1
Nonequilibrium dynamics in spin systems is a topic currently under intense investigation as it provides fundamental insights into thermalization, universality, and exotic transport…
Breaking Rayleigh's law with spatially correlated disorder to control phonon transport
Simon Thébaud, Lucas Lindsay, Tom Berlijn
Controlling thermal transport in insulators and semiconductors is crucial for many technological fields such as thermoelectrics and thermal insulation, for which a low thermal cond…
Magnon Orbital Angular Momentum of Ferromagnetic Honeycomb and Zig-Zag Lattices
R. S. Fishman, T. Berlijn, J. Villanova +1
By expanding the gauge for magnon band in harmonics of momentum , we demonstrate that the only observable component of the magnon orbital angular momen…
Exact Results for the Orbital Angular Momentum of Magnons on Honeycomb Lattices
Randy S. Fishman, Lucas Lindsay, Satoshi Okamoto
We obtain exact results for the orbital angular momentum (OAM) of magnons at the high symmetry points of ferromagnetic (FM) and antiferromagnetic (AF) honeycomb lattices in the pre…
