Mott Physics in Correlated Nanosystems: Localization-Delocalization Transition of Electrons by Exact Diagonalization Ab Initio Method

Józef Spałek

The electronic states of selected nanosystems are discussed within the Exact Diagonalization Ab Initio (EDABI) method. In particular, incipient Mott--Hubbard localization effects a…

A brief perspective of high temperature superconductivity in the cuprates: Strong correlations combined with superexchange match experiment

Józef Spałek

High temperature superconductivity encompasses the cuprates, nickelates, iron pnictides, and LaH compounds. The first three groups of compounds involve in the pairing electrons…

Degree of atomicity in the chemical bonding: Why to return to the H2 molecule?

Maciej Hendzel, Józef Spałek

We analyze two-particle binding factors for the case of \ch{H2} molecule with the help of our original Exact Diagonalization \textit{Ab Intio} (EDABI) approach. Explicitly, we rede…

Towards Complementary Characterization of the Chemical Bond

Maciej Hendzel, Maciej Fidrysiak, Józef Spałek

A precise discussion of a single bond requires consideration of two-particle wave function for the particles involved. Here we define and determine rigorously the intrinsic covalen…

Superconductivity in high- and related strongly correlated systems from variational perspective: Beyond mean field theory

Józef Spałek, Maciej Fidrysiak, Michał Zegrodnik +1

In this review, we single out selected universal features of high- and related systems, which can be compared with experiment. We start with the concept of real-space pairing,…

Many-particle covalency, ionicity, and atomicity revisited for a few simple example molecules

M. Hendzel, M. Fidrysiak, J. Spałek

We analyze two-particle binding factors of H2, LiH, and HeH+ molecules/ions with the help of our original exact diagonalization ab intio (EDABI) approach. The interelectronic corre…
