The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
space, is ideally suited for quantum control. Molecular angular momentum is naturally …

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

Altermagnetism has emerged as a third type of collinear magnetism. In contrast to standard
ferromagnets and antiferromagnets, altermagnets exhibit extra even-parity wave spin order …

Although the existence of nematic order in iron-based superconductors is now a well-
established experimental fact, its origin remains controversial. Nematic order breaks the …

Kamihara and coworkers' report of superconductivity at T c= 26 K in fluorine-doped
LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

Since the discovery of high T c iron-based superconductors in early 2008, more than 15,000
papers have been published as a result of intensive research. This paper describes the …

A fundamental and unconventional characteristic of superconductivity in iron-based
materials is that it occurs in the vicinity of two other instabilities. In addition to a tendency …

Whether a quantum critical point (QCP) lies beneath the superconducting dome has been a
long-standing issue that remains unresolved in many classes of unconventional …

High-transition temperature (high-T c) superconductivity in the iron pnictides or
chalcogenides emerges from the suppression of the static antiferromagnetic order in their …

Electronic nematicity, a unidirectional self-organized state that breaks the rotational
symmetry of the underlying lattice,, has been observed in the iron pnictide,,,, and copper …
