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

A hallmark of the phase diagrams of quantum materials is the existence of multiple
electronic ordered states, which, in many cases, are not independent competing phases, but …

The development of sensible microscopic models is essential to elucidate the normal-state
and superconducting properties of the iron-based superconductors. Because these …

Understanding the microscopic structure is often the first step in new materials discovery and
is essential to improve the materials functional properties. Neutron powder diffraction has …

Spontaneous symmetry breaking—the phenomenon in which an infinitesimal perturbation
can cause the system to break the underlying symmetry—is a cornerstone concept in the …

The neutron powder diffractometer POWGEN at the Spallation Neutron Source has recently
(2017–2018) undergone an upgrade which resulted in an increased detector complement …

Magnetism is widely considered to be a key ingredient of unconventional superconductivity.
In contrast to cuprate high-temperature superconductors, antiferromagnetism in most Fe …

In addition to the pressurized high-temperature superconductivity, bilayer and trilayer
nickelate superconductors La n+ 1 Ni n O 3 n+ 1 (n= 2 and 3) exhibit many intriguing …

The van der Waals ferromagnet F e 3 GeT e 2 has attracted great research attention recently
due to its extraordinary properties. Here, using high-resolution angle-resolved …

We present a self-consistent method based on first-principles calculations to determine the
magnetic ground state of materials, regardless of their dimensionality. Our methodology is …
