First-principles search of hot superconductivity in La-X-H ternary hydrides
Motivated by the recent claim of hot superconductivity with critical temperatures up to 550 K in La + x hydrides, we investigate the high-pressure phase diagram of compounds that may have formed in
Superconductivity in La andYhydrides: Remaining questions to experiment and theory
Recent reports of the superconductivity in hydrides of two different families (covalent lattice, as in SH3 and clathrate-type H-cages containing La and Y atoms, as in LaH10 and YH6) have revealed new
Effect of paramagnetic impurities on superconductivity in polyhydrides: $\textit{s}$-wave order parameter in Nd-doped LaH$_{10}$
Polyhydrides are a novel class of superconducting materials with extremely high critical parameters, which is very promising for applications. On the other hand, complete experimental study of the
High T c Superconductivity in Heavy Rare Earth Hydrides
Sulfur and lanthanum hydrides under compression display superconducting states with high observed critical temperatures. It has been recently demonstrated that carbonaceous sulfur hydride displays
Prediction of high- Tc superconductivity in ternary lanthanum borohydrides
The study of superconductivity in compressed hydrides is of great interest due to measurements of high critical temperatures (Tc) in the vicinity of room temperature, beginning with the observations
Second group of high-pressure high-temperature lanthanide polyhydride superconductors
Rare-earth polyhydrides formed under pressure are promising conventional superconductors, with the critical temperature ${T}_{c}$ in compressed ${\mathrm{LaH}}_{10}$ almost reaching room temperature.

Recent computational studies confirmed by experiment have shown the occurrence of superconductivity in the compound $$\hbox {H}_3$$H3S at a temperature, $$T_\mathrm{c}$$Tc, near 200 K when the
High-temperature superconductivity of uranium hydrides at near-ambient conditions
Solid metallic hydrogen is believed to be a nearly room-temperature superconductor [1], but its synthesis proved elusive because extremely high pressures well over 400 GPa are required [2]. Following
No Superconductivity in Iron Polyhydrides at High Pressures
Recently, P\'epin et al. reported the formation of several new iron polyhydrides FeH$_x$ at pressures in the megabar range, and spotted FeH$_5$, which forms above 130 GPa, as a potential
