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…
Raman Circular Dichroism and Quantum Geometry of Chiral Quantum Spin Liquids
Eduard Koller, Valentin Leeb, Natalia B. Perkins +1
We show that the quantum geometry of fractionalized spin excitations in Mott-insulating quantum spin liquids (QSL) gives rise to a finite Raman circular dichroism (RCD) signal. We…
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…
