Designing materials with advanced functionalities is the main focus of contemporary solid-
state physics and chemistry. Research efforts worldwide are funneled into a few high-end …

EPW is an open-source software for ab initio calculations of electron–phonon interactions
and related materials properties. The code combines density functional perturbation theory …

The correlation functions of quantum systems—central objects in quantum field theories—
are defined in high-dimensional space-time domains. Their numerical treatment thus suffers …

While hydrogen-rich materials have been demonstrated to exhibit high T c superconductivity
at high pressures, there is an ongoing search for ternary, quaternary, and more chemically …

For half a century after the discovery of superconductivity, materials exploration for better
superconductors proceeded without knowledge of the underlying mechanism. The 1957 …

Determining the range of validity of Migdal's approximation for electron-phonon (e-ph)
coupled systems is a long-standing problem. Many attempts to answer this question employ …

We explore the electronic and structural properties of F m 3¯ m Lu-HN structures with
specific N, H ordering due to their remarkably narrow hydrogen-based bands at the Fermi …

Unconventional superconductivity is commonly linked to electronic pairing mechanisms,
since it is believed that the conventional electron-phonon interaction (EPI) cannot cause …

We perform Eliashberg calculations for magnon-mediated superconductivity in a normal
metal, where the electron-magnon interaction arises from interfacial coupling to …

Quantum geometry characterizes the geometric properties of Bloch electrons in the wave
space, represented by the quantum metric and the Berry curvature. Recent studies have …
