The 2014-2015 prediction, discovery, and confirmation of record high temperature superconductivity above 200K in H$_3$S, followed by the 2018 extension to superconductivity in the 250-280K range in lanthanum hydride, marks a new era in the longstanding quest for room temperature superconductivity: quest achieved, at the cost of supplying 1.5-2 megabars of pressure. Predictions of numerous high temperature superconducting metal hydrides $XH_n$ ($X$=metal) have appeared, but are providing limited…

Optical properties of superconducting pressurized LaH10
Recently superconductivity has been discovered at around 200 K in a hydrogen sulfide system and around 260 K in a lanthanum hydride system, both under pressures of about 200 GPa. These
High-TC Superconductivity in Hydrogen Clathrates Mediated by Coulomb Interactions Between Hydrogen and Central-Atom Electrons
The uniquely characteristic macrostructures of binary hydrogen-clathrate compounds $M$H$_\textrm{n}$ formed at high pressure, a cage of hydrogens surrounding a central-atom host, is theoretically
Multiband nature of room-temperature superconductivity in LaH10 at high pressure
Recently, the discovery of room-temperature superconductivity (SC) was experimentally realized in the fcc phase of ${\mathrm{LaH}}_{10}$ under megabar pressures. This SC of compressed
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.
Anharmonic theory of superconductivity in the high-pressure materials
Electron-phonon superconductors at high pressures have displayed the highest values of critical superconducting temperature $T_c$ on record, now rapidly approaching room temperature. Despite the
High-temperature superconductivity on the verge of a structural instability in lanthanum superhydride
It is determined that the high-symmetry high-temperature superconducting Fm-3m phase of LaH10 can be stabilized at substantially lower pressures than previously thought, and a remarkable correlation between superconductivity and a structural instability indicating that lattice vibrations, responsible for the monoclinic structural distortions in LaH 10, strongly affect the superconducted coupling.

An overview and the latest status of the superconductivity of metal superhydrides under high pressure are discussed in this review article. The searching for near-room-temperature superconductors


What superconducts in sulfur hydrides under pressure and why
The recent discovery of superconductivity at 190~K in highly compressed H$_{2}$S is spectacular not only because it sets a record high critical temperature, but because it does so in a material that
Quantum Crystal Structure in the 250 K Superconducting Lanthanum Hydride
The discovery of superconductivity at 200 K in the hydrogen sulfide system at large pressures [1] was a clear demonstration that hydrogen-rich materials can be high-temperature superconductors. The
Superconductivity at 250 K in lanthanum hydride under high pressures
A lanthanum hydride compound at a pressure of around 170 gigapascals is found to exhibit superconductivity with a critical temperature of 250 kelvin, the highest critical temperature that has been confirmed so far in a superconducting material.

Abstract Due to its low atomic mass, hydrogen is the most promising element to search for high-temperature phononic superconductors. However, metallic phases of hydrogen are only expected at extreme
Compressed sodalite-like MgH6 as a potential high-temperature superconductor
Recently, an experimental work reported a very high Tc of ∼190 K in hydrogen sulphide (H2S) at 200 GPa. The search for new superconductors with high superconducting critical temperatures in
Superconductive sodalite-like clathrate calcium hydride at high pressures
In the stoichiometry CaH6 a body-centered cubic structure with hydrogen that forms unusual “sodalite” cages containing enclathrated Ca stabilizes above pressure 150 GPa, and the resultant dynamic Jahn–Teller effect helps to enhance electron–phonon coupling and leads to superconductivity of CaH 6.

Conventional superconductivity at 203 kelvin at high pressures in the sulfur hydride system
S sulfur hydride is investigated, and it is argued that the phase responsible for high-Tc superconductivity in this system is likely to be H3S, formed from H2S by decomposition under pressure, which raises hope for the prospects for achieving room-temperature super conductivity in other hydrogen-based materials.
