Webhelicity of incident photons and thus is related to the chiral phonon in Fe 3 GeTe 2. Moreover, we confirm the spin-phonon coupling effects via a combined analysis of the anomalous phonon energies and linewidths below T c. Such coupling between lattice vibrations and magnetism strongly enhances the Raman susceptibility in Fe 3 GeTe 2 WebAbstract. MnBi 2 Te 4 represents a new class of magnetic topological insulators in which novel quantum phases emerge at temperatures higher than those found in magnetically doped thin films. Here, we investigate how couplings between electron, spin, and lattice are manifested in the phonon spectra of few-septuple-layer thick MnBi 2 Te 4.

WebJan 1, 2024 · Chiral symmetry breaking of phonons plays an essential role in emergent quantum phenomena owing to its strong coupling to spin degree of freedom. However, direct experimental evidence of the chiral phonon–spin coupling is lacking. In this study, we report a chiral phonon–mediated interlayer exchange interaction in atomically … WebDiscovered in high-energy physics, the chiral anomaly has recently made way to materials science by virtue of Weyl semimetals (WSM). Thus far, the main efforts to probe the chiral anomaly in WSM have concentrated on el… shrubs christmas lights

We apply our method to various semiconductors (Si and GaAs) and two-dimensional (2D) materials (graphene) as representative case studies. The magnetoresistance, Hall mobility and Hall factor in Si and GaAs are in very good agreement with experiments.
