Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

A Majorana fermion is a fermionic particle that is its own antiparticle. Since the theoretical
discovery by Ettore Majorana in 1937, the exotic particle has long been searched in particle …

The recent discovery of superconductivity in La 3 Ni 2 O 7 with T c≃ 80 K under high
pressure opens up a new route to high-T c superconductivity. This material realizes a bilayer …

Numerical results for ground-state and excited-state properties (energies, double
occupancies, and Matsubara-axis self-energies) of the single-orbital Hubbard model on a …

In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

Strong interactions in many-body quantum systems complicate the interpretation of charge
transport in such materials. To shed light on this problem, we study transport in a clean …

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

The Hubbard model represents the fundamental model for interacting quantum systems and
electronic correlations. Using the two-dimensional half-filled Hubbard model at weak …

The aim of this review article is to assess the descriptive capabilities of the Hubbard‐rooted
LDA+ U method and to clarify the conditions under which it can be expected to be most …

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 …
