The rapid development of information technology has led to urgent requirements for high
efficiency and ultralow power consumption. In the past few decades, neuromorphic …

It has long been thought that strongly correlated systems are adiabatically connected to their
non-interacting counterpart. Recent developments have highlighted the fallacy of this …

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

Strong electronic correlations are often associated with the proximity of a Mott-insulating
state. In recent years however, it has become increasingly clear that the Hund's rule …

A review of the basic ideas and techniques of the spectral density-functional theory is
presented. This method is currently used for electronic structure calculations of strongly …

We used resonant inelastic x-ray scattering to reveal the nature of magnetic interactions in
Sr 2 IrO 4, a 5 d transition-metal oxide with a spin-orbit entangled ground state and J eff= 1/2 …

Flat-band materials such as the kagome metals or moiré superlattices are of intense current
interest. Flat bands can result from the electron motion on numerous (special) lattices and …

We show that there is a close correspondence between the physical properties of
holographic metals near charged black holes in anti–de Sitter (AdS) space, and the …

The calculation of the electronic properties of materials is an important task of solid-state
theory, albeit particularly difficult if electronic correlations are strong, eg, in transition metals …

Condensed-matter analogues of the Higgs boson in particle physics allow insights into its
behaviour in different symmetries and dimensionalities. Evidence for the Higgs mode has …
