Abstract
A formulation of the effective hybridization model is
developed which describes Fermi-liquid Kondo and fractionalized Fermi-liquid
(deconfinement spin-liquid-like) states with account of possible
magnetic ordering. A unified consideration of charge and magnetic
fluctuation is performed within perturbation theory in hybridization and
within gauge field treatment. The corresponding contributions to specific
heat and resistivity are compared.
