Optical phonons coupled to a Kitaev spin liquid
A. Metavitsiadis, W. Natori, J. Knolle +1
Emergent excitation continua in frustrated magnets are a fingerprint of fractionalization, characteristic of quantum spin-liquid states. Recent evidence from Raman scattering for a…
Finite-momentum energy dynamics in a Kitaev magnet
Alexandros Metavitsiadis, Wolfram Brenig
We study the energy-density dynamics at finite momentum of the two-dimensional Kitaev spin-model on the honeycomb lattice. Due to fractionalization of magnetic moments, the energy…
Enhancement of magnetization plateaus in low dimensional spin systems
Alexandros Metavitsiadis, Christina Psaroudaki, Wolfram Brenig
We study the low-energy properties and, in particular, the magnetization process of a spin-1/2 Heisenberg sawtooth and frustrated chain (also known as zig-zag ladder) wit…
Phonon renormalization in the Kitaev quantum spin liquid
Alexandros Metavitsiadis, Wolfram Brenig
We study the self-energy of phonons, magnetoelastically coupled to the two-dimensional Kitaev spin-model on the honeycomb lattice. Fractionalization of magnetic moments into mobile…
Heat transport in the anisotropic Kitaev spin liquid
Angelo Pidatella, Alexandros Metavitsiadis, Wolfram Brenig
We present a study of longitudinal thermal transport in the Kitaev spin model on the honeycomb lattice, focusing on the role of anisotropic exchange to cover both, gapless and gapp…
Spin liquid fingerprints in the thermal transport of a Kitaev-Heisenberg ladder
Alexandros Metavitsiadis, Christina Psaroudaki, Wolfram Brenig
We identify fingerprints of a proximate quantum spin-liquid (QSL), observable by finite-temperature dynamical thermal transport within a minimal version of the idealized Kitaev mod…
