MARGINAL FERMI LIQUID IN STRONGLY CORRELATED SPIN SYSTEMS
Keyword(s):
We consider the consequences of the separation of spin and charge degrees of freedom in 2 + 1 D strongly correlated spin systems. Self-consistent spin and charge motions induced by doping in sites of ground and dual lattices form such a spectrum of quasiparticles which together with the dispersionless character of the collective excitation spectrum and the chemical potential pinning in the band center yield the necessary behavior to support the theory of marginal Fermi liquid formulated by C. M. Varma et al. (Phys. Rev. Lett.63, 1996 (1989)).
