Understanding cuprate superconductors requires better knowledge of the microscopic structure of their charge-density waves (CDW). Here, the authors report evidence that the long-range CDW order in YBa2Cu3Oy has a local commensurate period of three un

Strong electronic correlations are expected to generate novel behaviour in materials possessing exotic massless electrons with a relativistic nature. Here, the authors demonstrate the reshaping of tilted Dirac cones and ferrimagnetism associated with

The Coulomb interaction among massless chiral particles harbors unusual emergent phenomena in solids beyond the conventional realm of correlated electron physics. An example of such an effect is excitonic condensation of interacting massless Dirac fe

In order to identify the mechanism responsible for the formation of charge-density waves (CDW) in cuprate superconductors, it is important to understand which aspects of the CDW’s microscopic structure are generic and which are material-dependent.

The mechanism of unconventional superconductivity, such as high-temperature-cuprate, Fe-based, and heavy-fermion superconductors, has been studied as a central issue in condensed-matter physics. Spin fluctuations, instead of phonons, are considered t

This work explores excitonic pairing instability in Zeeman-split two- dimensional Dirac cones with titled valleys, considering self-energy corrections via renormalization-group technique and a ladder-type vertex. The authors demonstrate how the pairi

We present a $^{35}$Cl NMR study for spin $S=1/2$ perfect kagome antiferromagnet Ca-kapellasite (CaCu$_{3}$(OH)$_{6}$Cl$_{2}\cdot$0.6H$_{2}$O) with a magnetic transition at $T^{\ast}=7.2$ K. The static magnetic structure in the ground state has been
