Quantum Reorientational Excitations in the Raman Spectrum of Hydrogen
Philip Dalladay-Simpson, Eric Edmund, Huixin Hu +2
Low-frequency Raman peaks, below 250 cm-1, are observed in hydrogen between 2-174 GPa and 13-300 K. The origin of these features is attributed to reorientational transitions (Delta…

Raman fingerprint of high-temperature superconductivity in compressed hydrides
Philip Dalladay-Simpson, Guglielmo Marchese, Zi-Yu Cao +5
The discovery of high-temperature superconductivity in hydrogen-rich compounds under extreme pressures has prompted great excitement, intense research, but also debate over the pas…
