WebJan 28, 2024 · When chiral symmetry breaks in a crystal, chiral phonons emerge and can couple to spins leading to phenomena such as phonon Hall effect, optically driven effective magnetic field, AC Stark effect, topologically induced viscosity split, and pseudogap phase, as summarized in Table 1 ( 1 – 16 ). WebUsing an {\it ab initio} approach, we report a phonon soft mode in the tetragonal structure described by the space group $I4_{1}22$ of the $1$ K $5d$ superconductor ... WebMar 22, 2024 · Manley et al. argue that this splitting occurs because these phonons hybridize with local, harmonic lattice vibrations associated with polar nanoregions. We show that splitting is absent when the measurement is made using a different neutron wavelength, and we suggest an alternative interpretation. how to root azaleas from clippings
