The quasi-two-dimensional kagome materials AV3Sb5 (A= K, Rb, Cs) were found to be a
prime example of kagome superconductors, a new quantum platform to investigate the …

We review the physics of pair-density wave (PDW) superconductors. We begin with a
macroscopic description that emphasizes order induced by PDW states, such as charge …

Understanding the competition between superconductivity and other ordered states (such as
antiferromagnetic or charge-density-wave (CDW) state) is a central issue in condensed …

A hallmark of many unconventional superconductors is the presence of many-body
interactions that give rise to broken-symmetry states intertwined with superconductivity …

We report high resolution polar Kerr effect measurements on CsV 3 Sb 5 single crystals in
search of signatures of spontaneous time-reversal symmetry breaking below the charge …

The concept that superconductivity competes with other orders in cuprate superconductors
has become increasingly apparent, but obtaining direct evidence with bulk-sensitive probes …

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 …

Variational studies of the tJ model on the square lattice based on infinite projected-
entangled pair states confirm an extremely close competition between a uniform d-wave …

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 …
