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 …

Superconductivity is a remarkably widespread phenomenon that is observed in most metals
cooled to very low temperatures. The ubiquity of such conventional superconductors, and …

The pursuit of discovering new high-temperature superconductors that diverge from the
copper-based model,–has profound implications for explaining mechanisms behind …

Recently, the bulk nickelate La 3 Ni 2 O 7 is reported to show a signature of high-
temperature superconductivity under high pressure above 14 GPa [H. Sun, Nature (London) …

Designing materials with advanced functionalities is the main focus of contemporary solid-
state physics and chemistry. Research efforts worldwide are funneled into a few high-end …

Abstract Two-dimensional (2D) materials with multiphase, multielement crystals such as
transition metal chalcogenides (TMCs)(based on V, Cr, Mn, Fe, Cd, Pt and Pd) and transition …

We investigate topological properties in the Fe (Te, Se) thin films. We find that the single
layer FeTe 1− x Se x has nontrivial Z 2 topological invariance which originates from the …

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 …

During the last century, inorganic oxide compounds laid foundations for materials synthesis,
characterization, and technology translation by adding new functions into devices previously …

We report the observation of superconductivity in infinite-layer Ca-doped LaNiO2 (La1− x Ca
x NiO2) thin films and construct their phase diagram. Unlike the metal-insulator transition in …
