The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Two hydrogen-rich materials, H 3 S and LaH 10, synthesized at megabar pressures, have
revolutionized the field of condensed matter physics providing the first glimpse to the …

The discovery of superconductivity at 200 kelvin in the hydrogen sulfide system at high
pressures demonstrated the potential of hydrogen-rich materials as high-temperature …

The physical description of all materials is rooted in quantum mechanics, which describes
how atoms bond and electrons interact at a fundamental level. Although these quantum …

Iron with a large magnetic moment was widely believed to be harmful to the emergence of
superconductivity because of the competition between the static ordering of electron spins …

Superconductivity with T c≈ 15 K was recently found in doped NdNiO 2. The Ni 1+ O 2
layers are expected to be Mott insulators, so hole doping should produce Ni 2+ with S= 1 …

The measurement of superconductivity at above 200 K in compressed samples of hydrogen
sulfide and in lanthanum hydride at 250 K is reinvigorating the search for conventional high …

Graphene's success has shown that it is possible to create stable, single and few-atom-thick
layers of van der Waals materials, and also that these materials can exhibit fascinating and …

Emergent electronic phenomena in iron-based superconductors have been at the forefront
of condensed matter physics for more than a decade. Much has been learned about the …

The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …
