Elements in the alkali metal series are regarded as unlikely superconductors because of their monovalent character. A superconducting transition temperature as high as 20 K, recently found in compressed lithium (the lightest alkali element), probably arises from pressure-induced changes in the conduction-electron band structure. Superconductivity at ambient pressure in lithium has hitherto remained unresolved, both theoretically and experimentally. Here we demonstrate that lithium is a… Expand
High-pressure superconducting phase diagram of 6Li: Isotope effects in dense lithium
This study measured the superconducting transition temperature of 6Li between 16 and 26 GPa, and reports the lightest system to exhibit superconductivity to date, and presents evidence that properties of lithium at low temperature may significantly be dominated by its lattice quantum dynamics.

S-band metals such as alkali and alkaline earth metals do not undergo a superconducting transition (SCT) at ambient pressure, but their high-pressure phases do. By contrast, room-temperature stableExpand
Pressure-induced reappearance of superconductivity in the oC24 phase of lithium
Abstract Elements with low atomic numbers are expected to have high superconducting transition temperatures (Tc). Lithium, the lightest metallic element, has therefore been extensively investigatedExpand
Superconductivity in the metallic elements at high pressures
Abstract Although the highest superconducting critical temperature, T c , found in an elemental solid at ambient pressure is 9.2 K (niobium), under the application of ultra-high pressures, severalExpand
Recent studies in superconductivity at extreme pressures
Studies of the effect of high pressure on superconductivity began in 1925 with the seminal work of Sizoo and Onnes on Sn to 0.03 GPa and have continued up to the present day to pressures in the 200 -Expand
Evidence for superconductivity in Rb metal above 55 GPa pressure
The only alkali metal known to be superconducting at ambient pressure is Li at 0.4 mK. Under 30 GPa pressure \textit{T}$_{c}$ for Li rises to 14 K. In addition, nearly 50 years ago the heavy alkaliExpand
Nuclear ordering and superconductivity in lithium
Lithium metal constitutes a unique system of nuclear spins and conduction electrons, where the energy scales of the collective behavior among the two distinct, though interpenetrating, subsystems areExpand
A perspective on conventional high-temperature superconductors at high pressure: Methods and materials

Two classes of superconductors discovered in our material research: Iron-based high temperature superconductor and electride superconductor

Superconductivity in compressed lithium at 20 K
It is shown that Li becomes superconducting at pressures greater than 30 GPa, with a pressure-dependent transition temperature (Tc) of 20 K at 48  GPa, which is the highest observed Tc of any element; it confirms the expectation that elements with low atomic numbers will have high transition temperatures, and suggests that metallic hydrogen will have a very high Tc.
