The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

In this article, I review progress towards an understanding of the normal state (in-plane)
transport properties of high-T c cuprates in the light of recent developments in both …

The latest discovery of high temperature superconductivity near 80 K in La3Ni2O7 under
high pressure has attracted much attention. Many proposals are put forth to understand the …

Proximity to a Mott insulating phase is likely to be an important physical ingredient of a
theory that aims to describe high-temperature superconductivity in the cuprates. Quantum …

Cuprate superconductors have the highest critical temperatures (T c) at ambient pressure,
yet a consensus on the superconducting mechanism remains to be established. Finding an …

With recent discoveries of superconductivity in infinite–layer nickelates and in La 3 Ni 2 O 7
under high pressure, new opportunities appeared that yet another family of high …

Crystal geometry can greatly influence the emergent properties of quantum materials. As an
example, the kagome lattice is an ideal platform to study the rich interplay between topology …

The question of whether one should speak of a “pairing glue” in the Hubbard and tJ models
is basically a question about the dynamics of the pairing interaction. If the dynamics of the …

We review a number of experimental techniques that are beginning to reveal fine details of
the bosonic spectrum α 2 F (Ω) that dominates the interaction between the quasiparticles in …

We use the local-density approximation in combination with the dynamical mean-field theory
to carry out a comparative investigation of a typical electron-doped and a typical hole-doped …
