Thermodynamics of weakly coupled Falicov-Kimball chains from renormalization-group theory
Jozef Sznajd
The linear perturbation renormalization group is used to study spinless two-band fermion chains at half-filling. The model consists of two species of spinless fermions, namely loca…

Linear perturbation renormalization group method for Ising-like spin systems
J. Sznajd
The linear perturbation group transformation (LPRG) is used to study the thermodynamics of the axial next-nearest-neighbor Ising model with four spin interactions (extended ANNNI)…
