摘要：

We study the one-dimensional t-J model in a staggered magnetic field by a variational calculation based on the string picture. Our key assumption is the separation of energy scales between rapid incoherent hole motion on scale t and slow coherent motion on scale J. We discuss pair formation and phase separation in the hole liquid and find good agreement with exact diagonalization of small clusters.
