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 …

Flat-band materials such as the kagome metals or moiré superlattices are of intense current
interest. Flat bands can result from the electron motion on numerous (special) lattices and …

The Kondo lattice—a matrix of local magnetic moments coupled through spin-exchange
interactions to itinerant conduction electrons—is a prototype of strongly correlated quantum …

Non-volatile phase-change memory devices utilize local heating to toggle between
crystalline and amorphous states with distinct electrical properties. Expanding on this kind of …

In the Kondo lattice model, the interaction of a lattice of localized magnetic moments with a
sea of conduction electrons induces rich quantum phases of matter, including Fermi liquids …

Strange metal behavior refers to a linear temperature dependence of the electrical resistivity
that is not due to electron–phonon scattering. It is seen in numerous strongly correlated …

We extend the theory of shot noise in coherent metals to shot noise in strange metals without
quasiparticle excitations. This requires a generalization of the Boltzmann equation with a …

We introduce an effective theory for quantum critical points (QCPs) in heavy-fermion
systems, involving a change in carrier density without symmetry breaking. Our theory …

Complex many-particle quantum entanglement is a central theme in two distinct major topics
in physics: the strange metal state found in numerous correlated electron compounds, and …

DMRG ground state search algorithms employing symmetries must be able to expand virtual
bond spaces by adding or changing symmetry sectors if these lower the energy. Traditional …
