In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

X-ray techniques have been used for more than a century to study the atomic and electronic
structure in practically any type of material. The advent of correlated electron systems, in …

We argue that the topological charge density wave phase in the quasi-2D Kagome
superconductor AV 3 Sb 5 is a chiral flux phase. Considering the symmetry of the Kagome …

Topological quantum chemistry and symmetry-based indicators have facilitated large-scale
searches for materials with topological properties at the Fermi energy (EF). We report the …

The search for quantum states arising from the interplay between correlation, frustration and
topology is a central topic for condensed-matter physics. Recently discovered non-magnetic …

Superconductivity often emerges in the proximity of, or in competition with, symmetry-
breaking ground states such as antiferromagnetism or charge density waves,,,,(CDW). A …

The understanding of the origin of superconductivity in cuprates has been hindered by the
apparent diversity of intertwining electronic orders in these materials. We combined …

The spectral energy gap is an important signature that defines states of quantum matter:
insulators, density waves and superconductors have very different gap structures. The …

This article reviews the static and dynamic properties of spontaneous superstructures
formed by electrons. Representations of such electronic crystals are charge density waves …

'Conventional'superconductivity, as used in this review, refers to electron–phonon-coupled
superconducting electron pairs described by BCS theory. Unconventional superconductivity …
