This review addresses the method of explicit calculations of interatomic exchange
interactions of magnetic materials. This involves exchange mechanisms normally referred to …

The principal purpose of this topical review is to single out some of the universal features of
high-temperature (high-T c) and related strongly-correlated systems, which can be …

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

In this work, we investigate collective electronic fluctuations and, in particular, the possibility
of the charge density wave ordering in an infinite-layer NdNiO2. We perform advanced many …

We present an extension of the quasiparticle self-consistent GW approximation (QS GW)[T.
Kotani, Phys. Rev. B 76, 165106 (2007) 10.1103/PhysRevB. 76.165106] to include vertex …

Recently fabricated InSe monolayers exhibit remarkable characteristics that indicate the
potential of this material to host a number of many-body phenomena. In this work, we …

The orbital-selective electronic behavior is one of the most remarkable manifestations of
strong electronic correlations in multiorbital systems. A prominent example is the orbital …

We identify the precise hallmarks of the local magnetic moment formation and its Kondo
screening in the frequency structure of the generalized charge susceptibility. The sharpness …

In this work we computed the phase diagram as a function of temperature and do** for a
system of lead adatoms allocated periodically on a silicon (111) surface. This Si (111): Pb …

While the breakdown of the perturbation expansion for the many-electron problem has
several formal consequences, here we unveil its physical effect: flip** the sign of the …
