Abstract

The d-wave RVB mean field theory for the t-J model is generalized to the inhomogeneous case to incorporate harmonic hole modulation manifestly. Numerical results show that there are a monotonous decrease of ground state energy with the increase of amplitude of modulation. The form of this dependence strongly suggests the existence of a nontrivial stripe phase of t-J model for different t/J, and doping values.
