Pressure is a fundamental thermodynamic variable that can be used to control the properties
of materials, because it reduces interatomic distances and profoundly modifies electronic …

Materials based on hydrides have been the linchpin in the development of several practical
energy storage technologies, of which the most prominent example is nickel–metal hydride …

Synchrotron sources with high photon flux, small source size, and broad energy range have
revolutionized ultrafine characterization of condensed matter. With the addition of the …

The recent theory-orientated discovery of record high-temperature superconductivity (T c∼
250 K) in sodalitelike clathrate LaH 10 is an important advance toward room-temperature …

A superconductor is a material that can conduct electricity without resistance below a
superconducting transition temperature, T c. The highest T c that has been achieved to date …

The study of superconductivity in compressed hydrides is of great interest due to
measurements of high critical temperatures (T c) in the vicinity of room temperature …

In the last five years a large number of new high-temperature superconductors have been
predicted and experimentally discovered among hydrogen-rich crystals, at pressures, which …

A superconducting critical temperature above 200 K has recently been discovered in H2S
(or D2S) under high hydrostatic pressure,. These measurements were interpreted in terms of …

We use first-principles calculations to study structural, vibrational, and superconducting
properties of H 2 S at pressures P≥ 200 GPa. The inclusion of zero-point energy leads to …

The quantum nature of the proton can crucially affect the structural and physical properties of
hydrogen compounds. For example, in the high-pressure phases, of H2O, quantum proton …
