Continuum model for the terahertz dielectric response of glasses
Tatsuya Mori, Hideyuki Mizuno, Yuzuki Motokawa +6
Boson peak dynamics in glasses produce a robust crossover in the terahertz (THz) dielectric response that standard Debye or Lorentz models do not capture. We develop a continuum de…
Relationship between the boson peak and first sharp diffraction peak in glasses
Dan Kyotani, Soo Han Oh, Suguru Kitani +10
Boson peak (BP) dynamics refers to the universal excitation in the terahertz region of glass. In this study, the universal dynamics of BP were quantitatively evaluated in various g…
Magnetic resonance frequency of two-sublattice ferrimagnet with magnetic compensation temperature
Kouki Mikuni, Toshiki Hiraoka, Takumi Kuramoto +5
Ferrimagnetic materials with a compensation temperature have recently attracted interest because of their unique combination of ferromagnetic and antiferromagnetic properties. Howe…
Observation of low-frequency Raman peak in layered WTe
Hirofumi Nema, Yasuhiro Fujii, Eiichi Oishi +1
WTe recently attracted considerable attention as a layered material exhibiting ferroelectricity, giant magnetoresistance, and pressure-induced superconductivity. In this study,…
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…
