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 …

Abinit is a material-and nanostructure-oriented package that implements density-functional
theory (DFT) and many-body perturbation theory (MBPT) to find, from first principles …

Magic-angle (θ= 1.0 5°) twisted bilayer graphene (MATBG) has shown two seemingly
contradictory characters: the localization and quantum-dot-like behavior in STM …

Recently, superconductivity with a T c up to 78 K has been reported in bulk samples of the
bilayer nickelate La 3 Ni 2 O 7 at pressures above 14 GPa. Important theoretical tasks are …

Altermagnetism is a newly identified fundamental class of magnetism with vanishing net
magnetization and time-reversal symmetry broken electronic structure. Probing the unusual …

Kagome-lattices of 3 d-transition metals hosting Weyl/Dirac fermions and topological flat
bands exhibit non-trivial topological characters and novel quantum phases, such as the …

Motivated by the report of superconductivity in bilayer La 3 Ni 2 O 7 at high pressure, we
examine the interacting electrons in this system. First-principles many-body theory is utilized …

ABSTRACT ABINIT is probably the first electronic-structure package to have been released
under an open-source license about 20 years ago. It implements density functional theory …

ABINIT is a package whose main program allows one to find the total energy, charge
density, electronic structure and many other properties of systems made of electrons and …

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 …
