Coherent heat-wave generation in SrTiO using stimulated light-scattering
Akitoshi Koreeda, Hideaki Oe, Takahiro Okada +1
Wave propagation of heat in solids, which is often called `second sound', has attracted increasing attention to its various potential applications such as in thermal diodes and wav…
Selective observation of enantiomeric chiral phonons in -quartz
Eiichi Oishi, Yasuhiro Fujii, Akitoshi Koreeda
We report anomalous circularly polarized Raman spectra of phonons in right- and left-handed quartzes. The phonon branches splitting from the E-mode at a finite wavenumber were foun…
Observation of quasi-elastic light scattering in BiFeO
Eiichi Oishi, Yasuhiro Fujii, Akitoshi Koreeda +2
We observed quasi-elastic light scattering (QELS) in BiFeO using Raman spectroscopy over a temperature range of 300-860 K. The QELS has two components: a narrow and broad compo…
