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

Symmetries play a crucial role in understanding phases of matter and the transitions
between them. Theoretical investigations of quantum models with SU (N) symmetry have …

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 …

While calculations and measurements of single-particle spectral properties often offer the
most direct route to study correlated electron systems, the underlying physics may remain …

Microscopically understanding competing orders in strongly correlated systems is a key
challenge in modern quantum many-body physics. For example, the study of magnetic …

Spin-or orbital-selective behaviors in correlated electron materials offer rich promise for
spintronics or orbitronics phenomena and applications deriving from them. Strong local …

We investigate the metal-to-insulator phase transition driven by the density-density
electronic interaction in the quarter-filled model on a cubic lattice with two orbitals split by a …

The phase diagrams of quasi two-dimensional organic superconductors display a plethora
of fundamental phenomena associated with strong electron correlations, such as …

The impact of leading collective electronic fluctuations on a free energy of a prototype 1D
model for molecular systems is considered within the recently developed fluctuating local …

The physics of doped Mott insulators is at the heart of strongly correlated materials and is
believed to constitute an essential ingredient for high-temperature superconductivity. In …
