This is a review of the Sachdev-Ye-Kitaev (SYK) model of compressible quantum many-
body systems without quasiparticle excitations, and its connections to various theoretical …

The appearance of the Planckian time τ Pl= ℏ/k BT is reviewed in both conventional and
unconventional metals. A pedagogical discussion of the various different timescales …

The anomalous transport of important materials such as high-temperature superconductors
and other 'bad metals' is not well understood theoretically. In an incoherent metal, transport …

We present a theoretical investigation of the electronic structure of rutile (metallic) and M 1
and M 2 monoclinic (insulating) phases of VO 2 employing a fully self-consistent …

We investigate the optical properties of the normal state of the infinite-layer La 1− x Sr x NiO
2 using density functional theory plus dynamical mean-field theory. We find a correlated …

Landau suggested that the low-temperature properties of metals can be understood in terms
of long-lived quasiparticles with all complex interactions included in Fermi-liquid …

In materials with strong electron-phonon (e-ph) interactions, the electrons carry a phonon
cloud during their motion, forming quasiparticles known as polarons. Predicting charge …

A comparative density functional plus dynamical mean field theory study of the pseudocubic
ruthenate materials CaRuO 3 and SrRuO 3 is presented. Phase diagrams are determined …

Hund metals are multi-orbital systems with moderate Coulomb interaction, U, among
charges and sizeable Hund's rule coupling, J (< U), that aligns the spins in different orbitals …

Physical properties of multi-orbital materials depend not only on the strength of the effective
interactions among the valence electrons but also on their type. Strong correlations are …
