Non-reciprocal circular dichroism of axial phonons coupled to ferro-rotational order
H. Y. Huang, G. Channagowdra, D. Banerjee +10
Circular dichroism (CD) in X-ray absorption, defined as the difference in absorption between opposite circular polarizations, is fundamentally enabled by the breaking of time-rever…
Altermagnetic boosting of chiral phonons
J. Okamoto, C. Y. Mou, H. Y. Huang +10
Chirality characterizes the asymmetry between a structure and its mirror image and underlies a wide range of chiral functionalities. In crystallographically chiral materials, phono…
Raman spectroscopy of NaCoSbO
Yu. S. Ponosov, E. V. Komleva, E. A. Pankrushina +2
Raman spectroscopy together with density functional calculations were used to study lattice dynamics in a layered honeycomb cobaltite NaCoSbO, which can host a field-in…
Rattling Phonon Modes in Quadruple Perovskites
Z. V. Pchelkina, E. V. Komleva, V. Yu. Irkhin +2
Rattling phonon modes are known to be origin of various anomalous physical properties such as superconductivity, suppression of thermal conductivity, enhancement of specific heat e…
