Superconductivity at high-pressures has attracted considerable interest after the report of a record critical temperature (${T}_{c}$) of 203 K in sulfur hydride (H${}_{3}$S) at 200 GPa. In this work, the authors predict several novel lithium-sulfur compounds at high pressure using evolutionary crystal structure prediction techniques and investigate their superconducting properties with density functional linear response calculations. The calculations reveal an intrinsic correlation between…

In the present work, first-principles methods are used in an attempt to predict the superconducting critical temperature (Tc) as a function of pressure (P) for three metal-hydride systems of the MH3 form, namely ScH 3, YH3, and LaH3 and are able to point out a general trend in the Tc-dependence on P.

An extensive structural study on solid H2S at pressure ranges of 10-200 GPa is performed through an unbiased structure prediction method based on particle swarm optimization algorithm and is able to establish stable metallic structures violating an earlier proposal of elemental decomposition into sulfur and hydrogen.

Chemical bonding in hydrogen and lithium under pressure.

The common tendency of compressed H and Li to adopt three-fold coordinated structures as found is explained by the fact that such structures are capable of yielding a profound pseudogap in the electronic densities of states at the Fermi level, thereby reducing the kinetic energy.
