In this overview I sketch briefly the path to the so-called {\em t-J model} derived for the first time 30 years ago and provide its original meaning within the theory of strongly correlated magnetic metals with a non-Fermi (non-Landau) liquid ground state. An emergence of the concept of {\em real space pairing}, is discussed in a historical prospective. A generalization of this model to the many-orbital situation is briefly discussed. The emphasis is put on didactical exposition of ideas, as… 
Fifty years of Hubbard and Anderson lattice models: from magnetism to unconventional superconductivity - A brief overview
We briefly overview the importance of the Hubbard- and Anderson-lattice models as applied to the explanation of high-temperature and heavy-fermion superconductivity. Application of the models during
A generalized mean-field theory for the t-J model: the single-pole COM solution
We have reported the most general mean-field approximation for the t-J model obtained in the framework of the Composite Operator Method within the simplest one-pole approximation. The

TLDR
The extended (statistically consistent, SCA) Gutzwiller-type approach to the periodic Anderson model (PAM) in an applied magnetic field and in the strong-correlation limit shows that in ferromagnetic phases the low-energy single-particle states are strongly affected by the presence of the applied magnetic fields.
Slave particle study of the strongly correlated electrons
Until three decades ago, our understanding of the condensed matter systems were based on two frameworks developed by Russian physicist Lev Landau: his theory of phase transition, and Fermi liquids.
Exchange interaction as the source of pairing in correlated electron systems: a brief overview
We address the question of real space pairing induced by exchange interaction, customarily associated with the presence of the broken-symmetry magnetism. For such mechanism of pairing, the appearance
Surprises in the t-J Model: Implications for Cuprates.
TLDR
An analysis of the t-J model in the slave boson formulation which accounts for strong correlations, focusing on fluctuation effects that have hitherto not received the attention they deserve, finds several interesting results including the instability of the d-wave superconducting state to internal phase fluctuations giving way to a time reversal broken d+is^{*} superconductor at low doping.
Doublon dynamics in the extended Fermi-Hubbard model
Two fermions occupying the same site of a lattice model with strongly repulsive Hubbard-type interaction U form a doublon, a long-living excitation the decay of which is suppressed because of energy
Antiferromagnetism, charge density wave, and d-wave superconductivity in the extended t-J-U model: role of intersite Coulomb interaction and a critical overview of renormalized mean field theory.
TLDR
The role of the intersite Coulomb interaction term V in stabilizing the CDW phase is concentrated on, and it is shown that the charge ordering appears only above a critical value of V in a limited hole-doping range δ.
