Statistically-consistent Gutzwiller approach and its equivalence with the mean-field slave-boson method for correlated systems
Jakub Jȩdrak, Jan Kaczmarczyk, Jozef Spałek
We propose a new method of solving a class of mean-field (MF) models, which is based on the Maximum Entropy (MaxEnt) principle with additional constraints included. Next, we show e…
Renormalized mean-field t-J model of high-Tc superconductivity: comparison with experiment
Jakub Jȩdrak, Jozef Spałek
Using an advanced version of the renormalized mean-field theory (RMFT) for the t-J model, we examine spin-singlet superconducting (SC) state of -symmetry. Overall do…
A statistically consistent variational approach to the renormalized mean-field theory of the t-J model: critical hole concentrations for a paired state
Jakub Jȩdrak, Jozef Spałek
Recently, Fukushima [Phys. Rev. B \textbf{78} 115105 (2008)] proposed a systematic derivation of the Gutzwiller approximation for the t-J model. In the present paper, using this ap…
A consistent statistical treatment of the renormalized mean-field t-J model
Jakub Jȩdrak, Jozef Spałek
A variational treatment of the Gutzwiller - renormalized t-J Hamiltonian combined with the mean-field (MF) approximation is proposed, with a simultaneous inclusion of additional co…
