The t-J model on the square lattice, close to the t-J z limit, is studied by quantum Monte Carlo techniques at finite temperature and in the underdoped regime. A variant of the Hoshen-Koppelman algorithm was implemented to identify the antiferromagnetic domains on each Trotter slice. The results show that the model at high enough temperature presents finite antiferromagnetic (AF) domains, which collapse at lower temperatures into a single ordered AF state. While there are domains, holes would…

The CuO/sub 2/ planes in the high-temperature superconductors are described by a two-dimensional Hubbard model and a pair of holes, which naively should be quite mobile, are found to be extremely heavy due to a previously unappreciated frustration effect that impedes their motion.

Holes in the t-J_z model: a thorough study

The t-J_z model is the strongly anisotropic limit of the t-J model which captures some general properties of the doped antiferromagnets (AF). The absence of spin fluctuations simplifies the

Charge and spin ordering and charge transport properties in a two-dimensional inhomogeneous t − J model

We study a two-dimensional $t\ensuremath{-}J$ model close to the Ising limit in which charge inhomogeneity is stabilized by an on-site potential ${e}_{s},$ by using diagonalization in a restricted

HOLE AND PAIR STRUCTURES IN THE T-J MODEL

Using numerical results from density matrix renormalization group (DMRG) calculations for the t-J model, on systems as large as 10\ifmmode\times\else\texttimes\fi{}7, we examine the structure of the

When holes are doped into an antiferromagnetic insulator they form a slowly fluctuating array of {open_quotes}topological defects{close_quotes} (metallic stripes) in which the motion of the holes

Mobility of the doped holes and the antiferromagnetic correlations in underdoped high- Tc cuprates.

An incoherent-metal picture and a charged-stripe scenario are discussed as candidates to account for these peculiar features of the metallic charge transport in the La2-xSrxCuO4 system.

The problem of two holes in the presence of strong antiferromagnetic fluctuations is revisited using computational techniques. Two-dimensional clusters and two-leg ladders are studied with the
