Event Picture:

For disordered systems, a universal excitation called boson peak appears in the terahertz range. In this study, we performed terahertz time-domain spectroscopy on an oxide glass with entropic elasticity: mixed alkali metal metaphosphate glass with the chemical composition Li0.25Na0.25K0.25Cs0.25PO3 (LiNaKCsPO3), to detect the boson peak. The obtained spectra were compared with results of low-frequency Raman scattering and low-temperature specific heat measurements.
