Emergence of multiple relaxation processes during low to high density transition in Au49Cu26.9Si16.3Ag5.5Pd2.3 metallic glass
Alberto Ronca, Antoine Cornet, Jie Shen +8
The existence of multiple amorphous states, or polyamorphism, remains one of the most debated phenomena in disordered matter, particularly regarding its microscopic origin and impa…
An underdog story: Re-emergence of a polar instability at high pressure in KNbO3
Mohamad Baker Shoker, Sitaram Ramakrishnan, Boris Croes +12
Ferroelectricity in perovskites is known to be suppressed by a moderate hydrostatic pressure. The notion that a polar instability should reappear in a higher pressure regime is wel…
Prediction and Synthesis of MgPtH: A Metallic Complex Transition Metal Hydride Stabilized at Ambient Pressure
Wencheng Lu, Michael J. Hutcheon, Mads F. Hansen +13
The low-pressure stabilization of superconducting hydrides with high critical temperatures (s) remains a significant challenge, and experimentally verified superconducting hyd…
Hydrogen-rich hydrate at high pressures up to 104 GPa
Alexander F. Goncharov, Elena Bykova, Iskander Batyrev +10
Gas hydrates are considered fundamental building blocks of giant icy planets like Neptune and similar exoplanets. The existence of these materials in the interiors of giant icy pla…
Signature of superconductivity in pressurized La4Ni3O10-x single crystals grown at ambient pressure
Feiyu Li, Yinqiao Hao, Ning Guo +4
Nickelates have attracted enormous attention since the discovery of high-temperature superconductivity in La3Ni2O7 under high pressure. However, whether superconducting nickelate s…
Polymorphism of monatomic iodine
Alexander F. Goncharov, Huawei Chen, Iskander G. Batyrev +8
We applied synchrotron single-crystal X-ray diffraction in a diamond anvil cell at 48-51 GPa and first-principles theoretical calculations to study the crystal structure of solid a…
