The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar
importance to correlated electron physics as the Ising model is to statistical mechanics or the …

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

In recent years, the notion of'Quantum Materials' has emerged as a powerful unifying
concept across diverse fields of science and engineering, from condensed-matter and …

Quantum impurity models describe an atom or molecule embedded in a host material with
which it can exchange electrons. They are basic to nanoscience as representations of …

A review of the basic ideas and techniques of the spectral density-functional theory is
presented. This method is currently used for electronic structure calculations of strongly …

The nature of the pseudogap phase of cuprates remains a major puzzle,. One of its
signatures is a large negative thermal Hall conductivity, whose origin is as yet unknown …

Despite twenty years of research, the phase diagram of high-transition-temperature
superconductors remains enigmatic,. A central issue is the origin of the differences in the …

Recently developed numerical methods have enabled the explicit construction of the
superconducting state of the Hubbard model of strongly correlated electrons in parameter …

We analyze charge order in hole-doped cuprates within the the spin-fermion model. We
show that a magnetically mediated interaction, which is known to give rise to d-wave …

Understanding the electron pairing in hole-doped cuprate superconductors has been a
challenge, in particular because the “normal” state from which it evolves is unprecedented …
