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 …

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 …

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

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

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 …

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 …

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 …

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

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 …

We demonstrate, using first-principles calculations, that the electronic structure of FeSe 1− x
Te x (x= 0.5) is topologically nontrivial and characterized by an odd Z 2 invariant and Dirac …
