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 …

Heusler compounds are a remarkable class of intermetallic materials with 1: 1: 1 (often
called Half-Heusler) or 2: 1: 1 composition comprising more than 1500 members. Today …

We report high transition temperature superconductivity in one unit-cell (UC) thick FeSe films
grown on a Se-etched SrTiO 3 (001) substrate by molecular beam epitaxy (MBE). A …

The response of the worldwide scientific community to the discovery in 2008 of
superconductivity at T c= 26 K in the Fe-based compound LaFeAsO1− x F x has been very …

We report the superconductivity at above 30 K in a FeSe-layer compound K 0.8 Fe 2 Se 2
(nominal composition) achieved by metal K intercalating in between FeSe layers. It is …

The recent discovery of possible high-temperature superconductivity in single-layer FeSe
films, has generated significant experimental and theoretical interest,. In both the cuprate …

Superconductivity develops in metals upon the formation of a coherent macroscopic
quantum state of electron pairs. Iron pnictides and chalcogenides are materials that have …

Pressure has long been recognized as a fundamental thermodynamic variable but its
application was previously limited by the available pressure vessels and probes. The …

The record superconducting transition temperature (T c) for the iron-based high-temperature
superconductors (Fe-HTS) has long been 56 K. Recently, in single-layer FeSe films grown …

The thermal conductivities of materials are extremely important for many practical
applications, such as in understanding the thermal balance and history of the Earth, energy …
