Formation of clusters in the two dimensional t-J model: The mechanism for phase separation

A. Fledderjohann, A. Langari, K. -H. Muetter

The emergence of phase separation is investigated in the framework of a 2D t-J model by means of a variational product ansatz, which covers the infinite lattice by two types of L x…

Formation of clusters in the ground state of the $t - J$ model on a two leg ladder

A. Fledderjohann, A. Langari, K. -H. Muetter

We investigate the ground state properties of the $t - J$ model on a two leg ladder with anisotropic couplings ( $t, α = J / t$ ) along rungs and ( $t^{'}, α^{'} = J^{'} / t^{'}$ ) along legs. We have impleme…
