Spin-lattice coupling induced chiral phonons and their signature in Raman Circular Dichroism
Eduard Koller, Swetlana Swarup, Johannes Knolle +1
Recent Raman experiments on the Kitaev material -RuCl have reported a finite Raman circular dichroism (RCD), revealing chiral phonon behaviour not expected from lattice symm…
Raman scattering from moiré phonons
Vitor Dantas, Héctor Ochoa, Rafael M. Fernandes +1
We develop a theoretical framework for probing moiré phonon modes using Raman spectroscopy, and illustrate it with the example of twisted bilayer graphene (TBG). These moiré phonon…
Spin-strain interactions under hydrostatic pressure in -RuCl
A. Hauspurg, Susmita Singh, T. Yanagisawa +5
We investigate the effects of hydrostatic pressure on -RuCl, a prototypical material for the Kitaev spin model on a honeycomb lattice with a possible spin-liquid ground stat…
Magnetic order through Kondo coupling to quantum spin liquids
M. A. Keskiner, M. Ö. Oktel, Natalia B. Perkins +1
We study the emergence of magnetic order in localized spins that interact solely through their coupling to a Kitaev-type spin liquid. Using three toy models -- the Kitaev model, th…
Ferrimagnetic Kitaev spin liquids in mixed spin 1/2 spin 3/2 honeycomb magnets
Willian Natori, Yang Yang, Hui-Ke Jin +2
We explore the potential experimental realization of the mixed-spin Kitaev model in materials such as ZrRuCl, where spin-1/2 and spin-3/2 ions occupy distinct s…
