The Ising version of the t-J model
Maciej M. Maska, Marcin Mierzejewski, Evgeny Kochetov
The t-J model is analysed in the limit of strong anisotropy, where the transverse components of electron spin are neglected. We propose a slave-particle-type approach that is valid…
Effective spin-fermion model for strongly correlated electrons
A. Ferraz, E. Kochetov
A modified spin-fermion model is proposed to describe the physics of the underdoped phase of the t-J model of strongly correlated electrons
Ising t-J model close to half filling: A Monte Carlo study
M. M. Maska, M. Mierzejewski, A. Ferraz +1
Within the recently proposed doped-carrier representation of the projected lattice electron operators we derive a full Ising version of the t-J model. This model possesses the glob…
Limitations of the mean field slave-particle approximations
E. A Kochetov, A. Ferraz
We show that the transformation properties of the mean field slave boson/fermion order parameters under an action of the global SU(2) group impose certain restrictions on their app…
